keyboard shortcuts no longer work after upgrade to ios 6
After upgrading to iOS 6, the keyboard shortcuts on my iPhone 4S no longer work. Not only that I can't change them either. If I add or delete a shortcut, it simply goes back to the way it was when I exit the settings and go back in. My iPad 2 doesn't have this problem, only my iPhone 4S.
I tried restarting as well as doing a reset (hold home and power button).
Any idea how to fix this?
iPhone 4S, iOS 5.1.1, AT&T 32 GB
