I upgraded my MobileMe account to iCloud this afternoon. It's working fine on my Mac. On my iPhone and iPad, when I try to go into settings to set up iCloud, I put in my id and password, click sign in, and then it crashes. If I go into mail contacts and calendars to try to disable my MobileMe account, it crashes before I can do anything. It does it on both the iPad and iPhone running iOS 5. Anyone having similar problems, or know what I can do to fix it?
