And there is nothing I can do about it until a new update is released.
This was the trap we fell into with my wife's iPhone - after dealing with stuff like this for the third time, we got tired of it and got her a Galaxy S II.
She has iPads where she works and they were updated - more issues. Seems like Apple could do more to address the issues these IOS updates cause (still, it seems to be a small percentage of folks having issues).
