Apple has just pushed out an update for all iPhone generations in the form of iPhone OS 3.1.2. Don't expect any major feature updates in this 241MB download, but do expect a few fixes to some annoying problems, most notably:

• Resolves sporadic issue that may cause iPhone not to wake from sleep
• Resolves intermittent issue that may interrupt cellular services until restart
• Fixes bug that could cause occasional crash during video stream

Now if only I could get an update that "Resolves issue where your stupid phone thinks headphones are plugged in all the time, even when they're not, so you can finally answer calls without a headset plugged in" I'd be a very happy human being. To get your update on, plug in your iPhone and click on Check for Updates in iTunes. Jailbreakers: You'll probably want to wait on this one. [via Gizmodo]
