iPhone Firmware 3.1.2 Released

Apple has released firmware update 3.1.2 (7D11) for iPhone/iPod Touch.

This is a minor update to firmware 3.1 that was released on September 9 2009 and supports iPhone, iPhone 3G and iPhone 3GS. There is a separate update for iPod Touch users.

For Rogers/Fido iPhone owners, there is no new carrier file and the modem firmware was retained at 05.11.07.


Below are the updates in firmware 3.1.2:

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

I have actually been looking forward to that second one, as that is something my iPhone 3GS is occasionally plagued with.

Remember, if your iPhone/iPod Touch is jailbroken and/or unlocked, you should not immediately update to 3.1.2, as you may lose both your jailbreak and unlock.

Note from the Dev Team Blog:
