- Fixes an issue that could cause camera flash to not go off
- Improves reliability of iPhone 5 and iPod touch (5th generation) when connected to encrypted WPA2 Wi-Fi networks
- Resolves an issue that prevents iPhone from using the cellular network in some instances
- Consolidated the Use Cellular Data switch for iTunes Match
- Fixes a Passcode Lock bug which sometimes allowed access to Passbook pass details from lock screen
- Fixes a bug affecting Exchange meetings"
That's a decent set of fixes, but contrary to earlier reports, apparently does nothing to help those affected by excessive data usage.
Unfortunately, word is that this update is causing the Facebook app to crash on startup. I'm holding off on updating until that's fixed (don't judge me), but as soon as it is, I'll update and start testing data usage.
