Instant Expert: Secrets & Features of iOS 4

Click Below to Read the Rest of This Article:  


The Safari browser in iOS 4 remains much the same as in previous versions except for the addition of Bing as a third search engine. As before, you can choose your search engine from the Safari section in the Settings app.


When entering information into the Search field, the enter button is now simply labeled “Search” instead of displaying the name of the specific Search engine.

Safari also now displays both suggestions and recent searches when entering information into the search field. Previously, only recent searches were displayed here.


Safari continues to support background audio streaming as in previous versions but can now be accessed from the playback controls in the same manner as other background audio apps.



The iPod application in iOS 4 now synchronizes playlist folders from iTunes and allows users to create and edit playlists on the device itself.

Folder Organization

Folders created in iTunes will now synchronize across to iOS 4 devices in the same way as on click wheel iPod models. The iPod application displays the folder structure under the “Playlists” section.


Create and Edit Playlists

iOS 4 now allows you to create and edit playlists directly on the device. This replaces the “On-The-Go” playlist from previous versions. New playlists can be given a name, and songs are then added to the playlist by selecting tracks in much the same way as they were for On-The-Go playlists.


Playlists can also be edited or deleted directly on the device, including adding new tracks, removing tracks, or simply reordering tracks. This includes both playlists created on the device and playlists originally synced from iTunes. Playlist changes made on the iOS device are synced back to iTunes if using automatic sync.

Album View

The iPod application now displays track listings from albums in a style similar to that used by the iTunes Store application. A larger thumbnail of album artwork is shown with some album information at the top of the screen and a shuffle button to immediately begin shuffled playback of the album.


Albums with multiple artists will show the individual artist names below the track names.

Lyrics and Podcast Info

When listening to a podcast episode, you can now tap on the artwork to display additional information, in the same way that the lyrics display works for music tracks.


An option is available under the iPod section in the Settings app to disable this feature for both lyrics and podcasts if you’d rather the overlay not appear when accessing the advanced track controls.


iPod Out

iOS 4 also includes a new feature called “iPod Out” that when used with compatible cars will provide an interface to navigate music, podcasts and audiobooks.


SMS and MMS Messages can now be searched from within the Messages app or from the global Spotlight Search. Within the Messages app, a Search field appears at the top of the screen in the same way as it does in other apps.

A character count is also available in the Messages app to keep track of how long your text messages are. The count can be toggled on or off from the Messages section in the Settings app. When enabled, the character count appears as soon as you reach the second line of your message.



The Notes app itself remains much the same as in previous versions except that Notes can now be stored with your mail account. This is enabled within the Mail, Contacts and Calendars settings screen for each account that you want to store Notes in. If Notes have been enabled for one or more of your Mail accounts, then you can specify the Default Notes account at the bottom of the Mail, Contacts and Calendars Settings.


Further, once you have specified one or more accounts for Notes storage, the Notes app will display a list of available accounts that you can choose from when viewing or creating notes.


Existing Notes will continue to be stored on your device unless you manually copy and paste them into a new note in a different account. There is no option to copy or move notes between accounts. New notes are created in either the currently displayed account or the Default account from Settings if you are in the “All Notes” section.

Other Changes

iOS 4 brings several other relatively minor changes in some of the built-in applications.

YouTube can now display videos in both portrait and landscape views. Oddly, playback will still begin in landscape view; you will need to tilt the device into landscape and back into portrait to re-orient the video.


The Maps and Compass apps now use the new compass arrow icon for displaying the current location rather than the reticle used in previous versions.

The Calculator and Voice Memos applications are sporting redesigned icons. The Calculator icon is the most dramatic change, and appears that it may have been updated to prevent confusion with the new Folder icon design.


A new feature is now available to keep Visual Voicemail messages on the phone even after they have been deleted from the server.

The iTunes Store app now supports background audio when streaming podcasts. This works only for podcast audio and not song previews.


The App Store now includes support for Gifting Apps directly from the device, a feature that first became available on the App Store via iTunes in late March.


The iPhone warning screen for incompatible accessories no longer makes any reference to Airplane mode nor provides any option for enabling it, but instead simply provides a warning about potential interference and a “Dismiss” button. Putting the newer iPhone models in Airplane Mode is less necessary than it was with the original iPhone, since when operating in 3G mode, these devices produce minimal interference with most speakers compared to the original EDGE iPhone.


Deleting applications from the device no longer results in a prompt to rate the app before deleting, removing a feature first added in iPhone OS 2.2 in the fall of 2008.

iOS 4 devices can now receive carrier settings updates over-the-air. Previously, these could only be applied over USB via iTunes.



iOS 4 represents the first iOS release to create a large rift between different iPhone and iPod touch models. Some of the distinctions began last year with advanced Bluetooth and MMS capabilities not coming to the original iPhone, but these were minor features compared to how far iOS 4 leaves behind older devices. The 2007 models—the original iPhone and iPod touch—aren’t even invited to the party, while the most significant new feature of iOS 4, multitasking, is completely unsupported on the 2008 iPhone 3G and second-generation iPod touch. The likely reason for these differences would seem to be performance related: Older devices are simply incapable of keeping up with the demands of iOS 4, at least to Apple’s satisfaction.

Performance of iOS 4 on iPhone 3G and second-generation iPod touch devices would seem to bear this out. iOS 4 seems a little bit sluggish at certain tasks, although not so much that the average user would have any reason to be concerned. It seems clear, however, that these older devices have reached the limits of what Apple is willing to try and squeeze out of them. On the other hand, the performance of iOS 4 on the more recent iPhone 3GS and third-generation iPod touch models is quite impressive, particularly when you consider how much more is going on under the hood. As more third-party multitasking apps come out, it remains to be seen whether this performance will hold up to the demands of these additional background processes.

Update or Wait?

As a completely free and significant upgrade for iPhone 3GS and third-generation iPod touch users, iOS 4 is definitely worth the upgrade. Multitasking alone will open up these devices to a whole new set of options that were previously unavailable. The decision for iPhone 3G and second-generation iPod touch owners may be a bit murkier due to the risks of slight performance hits and the fewer benefits that iOS 4 will offer on these devices. Users of these older devices will have a long list of enhancements available to them, but will be missing out on what is probably the key feature of iOS 4 and the dozens of apps that are sure to follow. The performance hit on these older devices is not significant enough for most users to care about, since users concerned with maximum speed and performance are probably already considering a newer device.

The iOS 4 update itself seems stable and there’s no reason to recommend against upgrading, with the highest risk being the upgrade process itself. However, as long as you have all of your media content in iTunes and have backed up your device then the only risk is the time it may take to reload all of your content.

Update: Several iPhone 3G users have reported extremely slow performance after updating to iOS 4, even after a full, clean restore of the iPhone. We have not experienced these problems on any of our own iPhone 3G devices that we have updated.

Best of all on updating my iTouch 2G (that i won on a iLouge art contest, thanks again) is that smart playlists that are not working at all on iOS3 are working 100% now. Just this feature working again makes updating worthwhile.

Posted by Walter Segundo on June 21, 2010 at 9:02 PM (CDT)


Where is the iPod out setting?  I have an Alpine iXA-W404 and the dock connection stopped working after I updated to iOS 4.  Thanks.

Posted by Me on June 21, 2010 at 11:30 PM (CDT)


Phil (#1) & Kelvin (#2): The MMS settings are carrier-specific and determined by carrier configuration files. If MMS is not appearing then it’s either been turned off under Messages in the Settings app or it has been disabled by your carrier—perhaps inadvertently by an incorrect configuration file in the update. Similarly, “Group Messaging” is likely appearing as a result of an AT&T specific configuration.  Since I don’t have that setting, I’m not entirely sure what it means.

I know that Rogers in Canada pushed out a carrier update a couple of days before the iOS 4 release, and reports are that iOS 4 should now be able to receive carrier updates over-the-air and not just via iTunes..

Me (#5): I suspect the iPod Out feature will require new accessories that have not as-yet been released, or in the very least some kind of firmware update to existing car systems. It’s unfortunate, but not surprising that iOS 4 broke the connection to the Alpine—such things have happened with prior updates also—but hopefully this is something that Alpine can fix for you with a firmware update, or that Apple can address in 4.0.1.

Posted by Jesse Hollington in Toronto on June 22, 2010 at 9:06 AM (CDT)


@Me.  I have the same Apline unit and the same problem.  The Apple Knowledge boards have posts with similar issues with Alpine.  Hopefully there will be a software fix very soon.

as mentioned in article that 3g users wont be d by lack of features in update because they will be updating to a faster model. ive only just bought my 3g and im made to feel as though my iphone is slow and outdated. to put this right my iphone is so much faster with n ew update im happy with what ive been given thanks. why would i want to spend another £400 on a new phone.

Hey i did the update and noticed that i cannot change the background of my wallpaper ( home menue) and or LOCK SCREEN seperately… just still works the same as before i did it… what do i do?

Posted by Matt on June 22, 2010 at 4:17 PM (CDT)


So I found a change of my own with Bluetooth audio.  Pre-iOS4, the volume level out of the iPod was locked so that you can only change the volume using the Bluetooth headset/headphone’s controls.  Now that audio output is variable which is great for Jabra Halo owners like myself.  The Jabra Halo’s lowest volume level is still too high for most people.  I can now listen to my podcasts at night without blowing my eardrums out.

#4 Walter: I had the same problem with Smart Playlists. Turning off “Live updating” solved the problem. I’m glad to hear this is no longer necessary.

Posted by JP on June 22, 2010 at 7:14 PM (CDT)


The ipod touch doesn’t support multi-tasking or the home page wallpaper. Just so everyone knows. They skimped on the Ipod.

Posted by Kevin on June 22, 2010 at 7:51 PM (CDT)


Actually, home wallpapers and multitasking are supported on the third-generation iPod touch—the 32GB and 64GB models released in the fall of 2009.  The 8GB, 16GB and 32GB iPod touch models released in the fall of 2008 are secone-generation iPod models and in the same category as the iPhone 3G in terms of lacking support for multitasking, home screen wallpapers, and Bluetooth keyboards. 

Keep in mind that as noted in the article, the 8GB iPod touch currently being sold by Apple is actually a second-generation iPod touch—the same model first released in the fall of 2008.  Last fall Apple merely updated the OS to 3.x and re-released it at a lower price, but the hardware is identical to the earlier model.

Posted by Jesse Hollington in Toronto on June 22, 2010 at 7:59 PM (CDT)


Originally a little miffed at Apple for not allowing Home screen wallpaper on the 3G but after a day of use, I’m beginning to think Apple should have added the iPhone 3G to the incompatible list alongside the original iPhone and iPod Touch. This thing is painfully slow now. Were it not for the combined Inbox feature I’d have already attempted a downgrade back to 3.1.3.

Posted by Paul on June 22, 2010 at 11:03 PM (CDT)


I just download it IOS 4 on my Iphone 3G. Thought that I could change my App home screen wallpaper but it does not support it. Not FAIR!! This phone is still on SALE and it should support it, It is not descontinued yet. To be honest, The only change I really need and like is the 5x Zoom for my cam. Thanks.

Posted by David on June 23, 2010 at 12:09 AM (CDT)


can you get an alert / reminder pop up for birthdays in the birthday calendar? Its no use if you cant get a reminder!

Posted by shaz on June 23, 2010 at 8:23 AM (CDT)


@David (#16): To be fair, the release notes did indicate which features were not compatible with older iPhone and iPod touch models.  Of course, who actually reads those ;)

@shaz (#17): Sadly, no. The BIrthdays calendar is read-only in the same way that iCal subscribed calendars are, so you can’t edit the events even to add a notification.

I updated to 4.0 on my iPod touch 3rd gen and everything that uses the Internet is extremely slow. I have rarely have had these problems before the update. I can’t be my Internet connection because my other wireless devices are working fine.

Posted by Henderson on June 23, 2010 at 9:25 AM (CDT)


Most of the “power” smartlist users on the forums are reporting that they’re as broken as ever. Perhaps they’ve got the code up to the “standards” of the 5G nano (which is still utterly borked), but actual, full smartlist support is still MIA.

I realize that this is of no consequence to most readers, but the continued silence on this issue in these reviews is troublesome. For people who manage their libraries and iPod family devices via smartlists, the fact that Apple hasn’t had them working properly on a single new device since the 4G nano should not be blithely glossed over.

Posted by Code Monkey in Midstate New York on June 23, 2010 at 9:39 AM (CDT)


Sorry to report but iPOS4 will be getting taken off my iPhone 3G as soon as I can.
It has resulted in a slow to respond device - simple thing like trying to send a text can be frustrating.
And, as a side note, the upgrade of iTunes to 9.2 has ended up with more freezes/crashes of iTunes in the last couple of days than in the last two years with previous versions of iTunes.

Once again, I failed to take heed of the old adage, once bitten, twice shy. I should have waited for the posts from frustrated upgraders finding their devices borked to appear on the internets…

All we need now is the BSOD…..

Posted by Bob Levens in UK on June 23, 2010 at 9:54 AM (CDT)


Was hesitant about updating my iPhone 3G (plan to upgrade to the new iPhone 4 within the next two weeks) from hearing about multiple people having slowdown issues.  I did a complete backup, restore, and restart and am not seeing much of the slowdown described.  That’s with a 16GB 3G that is nearly filled to capacity with content. 

Utilizing threaded emails and folders, obviously no multitasking, but happy with the update thus far.  My suggestion is to completely restore your phone for the update for anyone who is also wary or wishing to go back to the 3.1.3 firmware.

Posted by Marc on June 23, 2010 at 12:41 PM (CDT)


@ Jesse: Where is this “iPod Out” setting? You wonder above if it will be for new accessories yet to be released, or perhaps available when existing accessories receive their own software update. But wouldn’t the setting be on a menu now? (even if ineffective)

Since this feature was first identified in April, I haven’t seen any definitive explanation for what it is (or will be), any update?

Posted by rockmyplimsoul on June 23, 2010 at 1:19 PM (CDT)


@Code Monkey (#20): I’ve been seeing the same issues with Smart Playlists as before, so it almost wasn’t worth mentioning in the article. What is interesting, however, is that i’ve also seen one or two random problems with Smart Playlists not updating in iTunes after a sync, requiring a restart of iTunes to do so.  I haven’t yet been able to reproduce this problem, and have only seen it occur in one of my libraries, but it’s something to look out for nonetheless.

@Bob (#21): You’re the third person I know personally to have reported the same problems following a complete iPhone 3G upgrade, yet both of my own iPhone 3G devices perform more or less as well as they did before—not great, but acceptable. The only issue I had with one was that a bunch of orange “other” capacity was filled up following the restore that wasn’t taken up before, suggesting that the restored media files didn’t all get catalogued properly. A second manual backup-and-restore process, followed by resyncing the content from iTunes, seemed to solve that issue.

This might be a valuable suggestion for others as well—from at least one report I’ve received, it seems that it might be the upgrade-based backup/restore process in iTunes 9.2 that’s actually borked, and not the iPhone 3G itself.  A manually-initiated “restore” should work the same way it did in prior versions of iTunes, restoring only application data and settings and letting iTunes sync your media and actual apps on as it normally would.

Unfortunately, regressing an iPhone to 3.1.3 is going to be more trouble than it’s worth—iTunes itself won’t let you do this and you’ll have to resort to the jailbreak-style methods.

@rock (#23): Other than a few leaked images from internal SDK code, I haven’t seen any evidence of this yet either.  My guess is that this is something similar that will activate automatically once a compatible accessory is connected, and therefore doesn’t require a separate menu option. The early Nike+ support worked much the same way—it was invisible until you actually connected a Nike+ receiver, after which the settings and home screen application suddenly appeared.

My educated guess from everything I’ve seen thus far is that this is a method for actually displaying an Apple-generated user interface on compatible car equipment, rather than relying on their own UIs to try to navigate the iPod content directly.  This would certainly provide at least a more unified experience across multiple car systems, if not a better experience overall.

Posted by Jesse Hollington in Toronto on June 23, 2010 at 2:45 PM (CDT)


@Jesse (24), Yes, I suppose since it has been 2008 since Apple made a product that handled smartlists properly, the notable thing would be if they shipped something that restored smartlist support as opposed to keeping things status quo. Still, iOS 4 is notable in that the long standing sort order bug that has prompted 8 bajillion forum posts here and on the Apple forums was fixed, but live updating with any playlist reference or logic nesting is still broken. It’s enough of a change of the status quo I think it should have been mentioned just so people would know it’s no longer necessary to keep implementing the kludge fixes that have been recommended for so long (such as “Playlist IS Music” to intentionally break live updating). For the people using simpler smartlists, iOS 4 is an improvement.

Posted by Code Monkey in Midstate New York on June 23, 2010 at 3:01 PM (CDT)


@ Jesse (#24) No mention of “iPod Out” in the newly-released iOS 4 User Guide, so perhaps they canned it. If you’re right in that it was only intended for an Apple-generated user interface on an accessory, then perhaps it will be available with some future accessory— I doubt that existing hardware could support this unless the necessary hooks to do this have already been published.

On a somewhat positive note, my factory Honda stereo can now (partially) communicate with my 2G Touch running iOS 4—ever since OS 3 I’ve had to queue up an album or playlist before connecting the Touch because the navigation was neutered by the OS change from 2 to 3. Now I can at least select Playlists on the stereo, but I still can’t select Artists or Albums. Oh well ...

Posted by rockmyplimsoul on June 23, 2010 at 3:33 PM (CDT)


@Code Monkey (#25): True enough, and the reality is that I gave up on complex Smart Playlists some time ago as I became tired of things never quite working as expected. For simpler Smart Playlists, iOS 4 did in fact improve things—something I actually discovered a couple of months ago when the betas first came out.  At this point, though, I’m sort of wondering if on-device Smart Playlist updating is something Apple has given up on.  Generally, things work pretty well if you sync with iTunes, and clearly Apple (mistakenly) expects people to be syncing their devices on a regular basis.  I could forgive that assumption if they ever implemented an actual wireless sync solution, but since everything still runs only over USB, it’s a somewhat ridiculous assertion.

Rock (#26): Actually, it’s specifically mentioned in the iOS 4 release notes:

“iPod out to navigate music, podcasts and audiobooks through an iPod interface with compatible cars.”

I’m also expecting that it won’t appear until specific new accessories arrive, as opposed to supporting anything that’s currently out there. However, your experience with your Honda stereo makes it pretty obvious why Apple needs to push their own solution for this… the current implementation of car control systems for the iOS devices is a complete and utter mess right now.  Unfortunately, how much success Apple will have at pushing their own standards in the fact of the automotive industry remains to be seen. After all, remember how well the elimination of 12V FireWire charging went in terms of car accessories—most manufacturers completely ignored Apple’s recommendations until faced with actual, incompatible hardware.

Posted by Jesse Hollington in Toronto on June 23, 2010 at 3:53 PM (CDT)


This update would be awesome if it didn’t effing break everything on the phone! Now my iPod app doesn’t work at all suddenly…apparently leaving it sitting over night breaks apple products. While I hate apple’s designer products (quality gear at over-the-top pricing), I’ve always tried to support their iPods and iPhones, but again, apple proves their “superiority” by releasing another half-baked product and hoping all the tech nerds will fix it for them. Apple will never ever see another dime of my money.

Posted by Mark on June 23, 2010 at 8:49 PM (CDT)


I can no longer navigate the menus using the remote with my iHome iP1 Studio Series speaker system. I suspect it may have something to do with the new “iPod out” protocol.

Posted by Galley in Greenville, SC on June 23, 2010 at 10:32 PM (CDT)


I updated my iPhone 3G 8GB and actually noticed performance improvements.  It seems snappier than ever.

Now to be fair I did do a complete restore from a jailbreak before updating, so I’m sure that has a lot to do with the improved performance.  But I would say there is a noticeable difference between my phone and wife’s (never jailbroken, updated also)

I might start doing restores every once in awhile if it boosts performance like this!

Posted by Chris in KC on June 24, 2010 at 10:07 AM (CDT)


Safari on iOS4 was made to scroll much faster in long webpages.

I’m playing a PS2 game and was reading a very lengthy FAQ on but scrolling to the bottom required me swiping for a couple of minutes non-stop.

After I upgraded my 3G to iOS4 and went to check out the FAQ, I immediately noticed it took me less than 10 seconds to go from the top to nearly the end.

This is a very small detail that meant a lot to me.

Posted by Leo on June 24, 2010 at 11:03 PM (CDT)


One change I really like about the iOS 4 Address Book: it now aggregates Address Book items from my Mac/iPhone/MobileMe together. So, whereas previously when looking at “All Contacts” I would get the same Address Book items displayed multiple times because they come from different sources, now they are listed under one item with a “Unified Info” heading and at the bottom of the page you get a link to the individual Address Book items from each of the sources if you would choose to look at a single one of them. This used to drive me nuts, and kudos to Apple for figuring out an elegant solution! :)

Posted by Jooil on June 25, 2010 at 4:23 AM (CDT)


Has anyone experienced a drop in battery life performance after the iOS 4 update? I seem to notice a 10-15% drop in battery performance.

Posted by Jon on June 25, 2010 at 4:32 AM (CDT)


The Gmail archive/delete “bug” (I do not considering saving a mail I want to delete to be a “feature”) is not changed if you are using Gmail via the Exchange method, FYI.

Posted by Tape on June 25, 2010 at 7:33 AM (CDT)


@Jon (#33): Battery performance under iOS 4 may take a slight hit due to additional background processing, but I haven’t observed any significant differences in the testing I’ve been doing.  The iPhone 3GS seems to suffer slightly more in terms of battery life than the iPhone 3G, perhaps due to the multitasking features available on the newer hardware. Obviously, the addition of other background apps is going to have an impact on battery life as well, although it shouldn’t be significant unless these apps are actually running in the background (ie, playing music, tracking location, waiting for VoIP calls, etc).

@Tape (#34): That’s actually a Google problem and there’s really no way for Apple to “fix” it.  Exchange Servers have no concept of “archive” vs “delete” and of course Google Sync is simply mimicking the Exchange ActiveSync protocol and translating a “Delete” request sent from the iOS device into an archive request.  In essence, Google Sync is a “hack” of a protocol designed to work with Microsoft’s Exchange servers. There’s nothing in the Exchange ActiveSync protocol that would realistically allow Apple to do anything about this, except perhaps to force a delete to actually be a Move-to-Trash operation.  However, I don’t believe it’s appropriate or reasonable for Apple to rewrite a protocol designed expressly to work with Microsoft Exchange servers merely because Google has chosen to implement it in their own non-standard way.

Posted by Jesse Hollington in Toronto on June 25, 2010 at 8:47 AM (CDT)


Is there a setting that displays the battery as a percentage like in the screenshots? My iOS4 just has the battery icon with no percent, but it’s ATT, not Rogers. I don’t see a setting for this anywhere.

Posted by Nate on June 25, 2010 at 10:29 AM (CDT)


Well written as usual Jesse.  I am curious if you will be covering the horrible performance of IOS 4 on the iPhone 3G.  The new OS release turns a formerly usable, albeit a bit pokey device into a very beautiful rock, particularly when working with calendars.

Thanks as always for your work

Posted by Doc Chevalier on June 25, 2010 at 10:31 AM (CDT)


@Nate (36): The battery percentage option is only available on the iPhone 3GS, iPhone 4 and iPad and be found under Settings, General, Usage on the iPhone and Setting, General on the iPad. It was actually first introduced last year with the iPhone 3GS on iOS 3.0 and is not anything new on iOS 4. It remains unavailable on other iPhone and iPod touch devices.

@Doc Chevalier (#37): Thanks. We’re still looking into some of the reported performance issues with the iPhone 3G as the problem does not seem to occur on ALL iPhone 3G devices.  The two 3G units I have here do seem a bit slower, but remain usable for all of the existing apps—they only seem to struggle with some of the newer apps like iBooks which are specifically optimized for iOS 4 and the iPhone 4.  That said, I do know others who have had serious performance degradation after upgrading, but haven’t yet been able to figure out exactly why that is.

Posted by Jesse Hollington in Toronto on June 25, 2010 at 11:48 AM (CDT)


I have a 2nd gen. 32GB Touch, took the new 4.0, and lost 10GB of free space in the process.  Prior to the download, I had 15GB of free space, now I only have 5GB left.  The orange representing “other” on the sync bar was barely a blip before the download, now it covers 7 1/3 of the sync bars…it went from a few KBs to 10GBs.
WOW!  I’ve lost 10GBs of music space.  What happened?

Posted by jibbs41 on June 25, 2010 at 4:42 PM (CDT)


@#(36): Well, I have an iPod Touch (late 2008 model) and I had it jailbroken to where I could see the percetiage in the top corner. Now my performance on the iPod was slow so I unjailbroke it. But when I did that the percent still stayed in the corner. So you might be able to do that.

Posted by Koosko on June 25, 2010 at 8:07 PM (CDT)


Well I’d like to thank @ Jesse David Hollington in Toronto, for his aside (#24), in a reply to another poster, @Bob(#21).  It turned out to be that answer to my post question @ jibbs41(#39), about my losing 10GB of free space to the orange “other” on the bar at the bottom of the page.  I did the manual restore, and got back my 10GB of free space.  The orange “other” is now at 298MB.  Thank, you, thank you, thank you, kind sir.

Posted by Jibbs41 on June 25, 2010 at 9:51 PM (CDT)


Since upgrading my 3Gs to 4.0 I am unable to access Facebook apps (Mafia Wars and Farmville).  I have been advised to turn the device off and reset it.  I have tried both of these options 2x but with no luck.  Any other advise?

Posted by Ainslie on June 25, 2010 at 10:19 PM (CDT)


@Code Monkey (#20). I gave up on smartlists on my itouch ages ago, but there’s a brilliant iphone app called “SmartPlaylist” that lets you create smartlists on the fly. I deleted most of my saved play lists after using this app. Its just been updated to work on the new OS.

Thanks Jesse for a fantastic overview.

Updated my iPhone 3G and now my iPod is weirding out—I select a song to play (that’s always played before the update) and it brings it up on the screen but then skips over to some other song.  It is extremely frustrating. I’ve turned the phone off/on and re-synced on iTunes a few times to no avail. I still have the problem. I would not have updated had I known this.

Thanks, this was really helpful. Also, in the screen chits you had, the silver bar at the top had a little percentage sign next to the battery, how did it get there? Is it displaying the percentage of battery?

Music volume is lower after upgrade. Hopefully, they fix it.

i have the third generation ipod touch, and i updated to the iOS 4 firmware update. but when i go to set a home screen wallpaper i see that it says set to home screen but it scrolls past the option and only does lockscreen wallpaper. i took a screenshot really fast and i can show the options scrolling by. what should i do?

@Kelly (#46): Your iPod is probably a second generation iPod, which doesn’t support home screen backgrounds or fast-app switching, among other features.

As for this article, it was great and insightful. I just updated my iPod (also a second gen, sadly) and it was nice to learn exactly what I COULD do. I really love the idea of folders. Makes everything so much faster for me!

Installed 4.0 to my iPod Touch 3G (32GB). No slow-down problems, no iTunes crashes.

I’ve had none of the problems that I’ve been reading about in the comments.

Maybe your ipods just suck, guys? :P

I upgraded my itouch 3gto 4.0 but it won’t let me multitask or put a picture on the springboard. I can make folders though. Pls help!

i have the 2nd generation ipod touch. Have there been a lot of complaints of problems from users like myself or has it been minimal? also, will the upgrade delete notes, safari bookmarks, and little things like that or are they safe too with a back up? this article was very helpful. thanks so much :)

What the hell Apple? I have a 2g iPod touch that I got barely a month before the 3G iPod touch came out and I can’t get the 2 updates that I was looking forward to the most in this new ios.  And I feel bad for the people who have the 1g iPod.  Why does apple do this shit?  If this ticks anyone else off let me know because I’m half tempted to write a complaint to Apple.

Posted by Bob on July 22, 2010 at 10:51 PM (CDT)


Oh you should definitely write a complaint to apple. I have an 8gb ipod touch and i got it like 2 weeks ago, and i can’t multitask or ad a background?!?! what’s it doing for stupid apple anyway to screw over the 8gb ipod like that? And why would they make a new generation of ipod but only make some of the ipods compatible?!? That’s the gayest thing i’ve ever heard of. I hate apple their whole program sucks!!!!!!!!!

help! I just tried to update my touch to 4.0, and now it just shows me the apple icon. When I plug it in to my computer, it gives me a message that it has detected an ipod in recovery mode. I have tried to do a recovery to restore, but it says it can’t (unknown error (21)). What can I do?

For those of you who has the 2g 8 gb, it says a lot of the features only work on the 2g 16-32gb, and the 3g 32-64 gb. maybe thats why your ipods are getting messed up?

Posted by Chacha on August 30, 2010 at 12:07 AM (CDT)

4th. Generation iPod Touch. My location defaults to a point in Hawaii. How do I change this to automatically default to my present location. ie I am in South Africa and have never been in Hawaii. For instance if i take a photo and download it to iPhoto, then it shows the location as Hawaii.
