Apple released the first update to iOS 6 since it was released on September 19, 2012. iOS 6.0.1 was released via a free Over The Air (OTA) update to iPhone and iPad users running iOS 6.
Ironically, iOS 6.0.1 fixes a bug that prevents some iPhone 5s from downloading OTA updates. According to CNET, it does this by installing a special "iOS updater" app to help the process along. The app is removed from the device after 6.0.1 is installed.
Here's the full changelog:
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
I installed it on my iPhone 4 and iPad 3 without issue (so far), what about you?
