Dear all, appreciate your advice. Current: PC User account A with iTunes account A with iPhone A, PC User account B with iTunes account B with iPhone B. Want to be: PC user account A with iTunes account A with iPhone A, and PC user account A with iTunes account B with iPhone B. This is so that I can turn on wifi on my iPhones and my PC and have my iPhones auto-sync over wifi while I sleep. And I don't have to switch PC user accounts. Any advice on what I need to do. I don't have problems with the music as I have the original files for all the iPhones. I'm more worried about the game/user data on each iPhone which I cannot lose. Appreciate your advice. Thanks.
