Apple has released the first update of iOS6 today which fixes an issue with Microsoft Exchange meetings (among other things), where one invitee to a meeting would inadvertently delete an entire meeting by simply declining the invitation.
Many Corporate Microsoft Exchange users had to temporarily place IT policies in place preventing iPhone and iPad users from declining meetings as a temporary workaround.
Among other fixes, the update solves multiple security vulnerabilities including four security bugs in the kernel, WebKit and Passcode according to Apple's Security Advisory.
Here is a list of improvements and bug fixes provided by Apple:
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
