Common issue--wife, husband have two Ipads, one Apple ID for buying apps and books. I've been using IOS5 since first day but just got around to upgrading husband's Ipad yesterday. I didn't think this out before allowing Icloud to be his Apple ID also. I've searched and searched for answer and while I was able to change his Apple ID to allow us to Imessage if we choose I can't find anything that really works to allow me to change his Icloud ID to his new Apple ID so our Icloud backups, photostream, etc are separate. Any help appreciated.
