If you’re new to iOS—or just a casual user—you might not know that the Safari browser on your iPhone, iPod touch, or iPad has bookmarks just like the one on your PC or Mac. To access them, simply tap on the open book icon—located at the bottom of the screen on iPhone and iPod touch, and in the top bar on the iPad.
A list of links and folders will appear, headlined by your browsing history. If you’ve chosen to sync your bookmarks through iTunes (handled in the Info tab for your device) or via MobileMe, all of the bookmarks from your Mac or PC should be there as well.
To add a bookmark, simply tap the action icon and select Add Bookmark; this should sync back to your computer upon your next sync, or over the air if you’re a MobileMe subscriber.
