Though iOS 6.0.1 is a .x.x release it actually has a fair number of bug fixes.
Fixes a bug that prevents iPhone 5 from installing software updates wirelessly over the air
Fixes a bug where horizontal lines may be displayed across the keyboard
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 one about the horizontal lines on the keyboard was something I thought was wrong with my particular iPhone 5. I’m glad to know it will be fixed in this update.
