Just a quick question, is it possible to sync 2 iPhones on 1 computer? I have a friend who has an old computer that is on the fritz and she wanted to sync and backup her phone on another computer til she gets a new one. I read iphones can only be synced to one computer at a time but was wondering if you could sync another phone as a temporary solution-especially if you login as another user. Would it be different for Mac and PC?
