iPhone OS 3.1.2 Released


A month after Apple (s aapl) made iPhone OS 3.1 available, version 3.1.2 for the iPhone and iPod touch can now be downloaded via iTunes.


Besides achieving version synchronicity (3.1.1 came with the 3G iPod touch), the update addresses issues with waking from sleep, cellular network disruption, and crashes while streaming video.

The most notable problem, the “iPhone coma” issue, resulted in some iPhones becoming unresponsive, touch controls not working, and phone not ringing when called. This required a hard reboot, but that was only a workaround. It’s still too early to tell whether 3.1.2 is a true fix for that pernicious issue.

Unfortunately, what was not addressed in the terse update log at all was battery life. That’s a little irritating because the problem has been acknowledged by Apple as “under investigation.” While fixes for issues relating to loss of network connection or random crashing/freezing are always welcome, those issues seem to affect a relatively small number of users. The battery life problem likely impacts most iPhones, if not most iPhone owners, the latter being dependent on how the individual uses the iPhone. Still, one hopes there is an iPhone OS update coming that will address the power management issue, and sooner rather than later.

In addition to the iPhone OS update, there is also a carrier update, version 5.6, but no info on what it does.



This sucks to hear. I was hoping for good news about the battery issue, as I wanted to get the latest OS. I am on 2.2.1 which works well for me. I could care less about the new features, but Apple has the developers to make their apps only available for 3.0 or higher. This is BS! So now I have to choose between not getting new apps or risking having the same issues others are complaining about. Apple better watch it. When you are the hip thing you can fall fast and hard.

WTF I was updating my iPod touch to 3.1.2* and when restarting, windows decided to punch me in the face and my “device became unrecognizable” bullshit!!!!! Had to recover and restore… took hours!!

*never had any of the problems you all had.

My “iPhone coma” is not better with 3.1.2. I actually can’t even connect to iTunes anymore, there is an error about an unrecognized device. I guess I’ll re-re-install iTunes and see if that helps.

I shouldn’t have to spend this much time thinking about my *phone*.


I still have problems with my iPhone, they aren’t as frequent or as annoying as 3.1 but it’s still not good enough.

My phone still doesn’t like to answer calls when i wake it up, it still freezes when i try to enter my passcode and it still lags and subsequently freezes when i try open new apps.

It’s better than 3.1 but 3.0 was exponentially less frustrating..

This is not real good. iPhone 3G 16 MB. Battery drain is phenomenally fast. Phone is actually warm to the touch – even when not in use. Took it to the Apple store, they gave me a brand new one. Restored from back up. Installed the update – Same exact problem. I think Apple should look into this. I’m going to go back to the store tomorrow. Stay away!
