Apple has released iPhone OS 3.1.2, its first major update to the iPhone’s and iPod touch’s software since the launch of version 3.1 and 3.1.1, respectively, on September 9. According to Apple’s release notes, the update “[r]esolves [a] sporadic issue that may cause iPhone (or iPod touch) to not wake from sleep,” as well as an “intermittent issue that may interrupt cellular network services until restart.” It also fixes a bug that could cause occasional crashes during video streaming. iPhone OS 3.1.2 is available now for both iPhone and iPod touch users through the update feature in iTunes.

@Bielzebub: You risk a ruined jailbreak with ALL updates. If it doesn’t break you jailbreak, great. If it does, then don’t be surprised.

Any word on whether this fixes battery life issues introduced in 3.1.1?

Still no fix to iPod touch wifi? I am assume that replacing my second-hand router is my only solution.

Not so sure about that regarding #4. I use an airport extreme router, and have high speed cable as my internet, and have intermittent internet issues with my iPod Touch, so if that’s what you’re talking about, blame it on 3.0 on up. The most recent update (3.1.2 hasn’t changed a thing in that regard).

Clarification:
The iPod Touch is the 64GB, not a upgraded 32GB.
Airport Extreme Dual Band Router, (the most recent one that has been released), and only the iPod Touch has these intermittent dropouts with internet reception, though I own multiple other Wi-Fi devices. That may be the issue (the other Wi-Fi devices) but I don’t remember the Touch with 2.x software having these issues. I did return that Touch though for 32GB was not enough for me. Now I’m wishing I had held onto it and not updated, though the bluetooth addition is kind of nice.

Doesn’t allow my VOIP app, iCall, to work on 3G.

Checked last night and I can finally paste my password into the iTunes App Store again. I sorely missed this feature in 3.1.1

I have an iPhone and have wi-fi issues too; I use a Linksys wireless N router and it won’t log on. It’s really annoying as I have to reset the router and it works fine

When I upgraded by 2G to 3.1 there were instant wifi issues. Not being able to rollback to 2.2.1 I made an apointment at the Genius Bar. I explained my wifi problem since updating and asked the reck to please get me back to the original firmware. He told me that it couldn’t be done, then proceeded to run a few tests on my touch. To my surprise he ended up giving me another 2G. I asked if he would recomend trying the 3.1 again. He said “it’s up to you”, making me tend to believe I should stick with 2.2.1, which I have done. No more wifi problems. Oh, also the replacment has a 935 production date, so I doubt if it’ a rebuilt. Thank you Apple!

@DenCimm
Thats why you need to download 3G Unrestrictor from Cydia. it makes any application think you are using WiFi when you are actually using 3G/EDGE.
