I setup my iPhone 5 by restoring from iCloud backup. The restore appears to have completed, and I got an alert saying something to that effect (though it also said some items couldn't be restored and to connect to iTunes to restore music which I think is normal because music is not in the iCloud backup). So I connected to iTunes and loaded up the iPhone with all my music and that has completed as well. Everything looks good. However, when I go to Settings -> iCloud -> Backup & Restore, the backup option is greyed out with a message saying that this iPhone is currently being restored. But it's been hours since it appears to have finished restoring. I suppose I could tap Stop Restoring iPhone. But that sounds dangerous. Any suggestions? Btw, I am using latest version of iTunes. Only thing out of the ordinary is that the iCloud backup is from my iPhone 4S running iOS 5.1.1. Should I have upgraded my old iPhone to iOS6 before doing the backup? Any other suggestions?
