We currently have 4 iPhones. We all have same iTunes user name and password. We all have different iCloud user names and passwords. It was suggested here that a separate iCloud user name and password to use with iCloud is best in a thread a while back. So now each iPhone has an iTunes same user name for iTunes/app purchases and each iPhone has their own iCloud user name for iCloud related stuff. This is making it confusing. The iTunes user name which is a gmail email address has been used for app purchases. What I did was changed all the iPhones to one user name for iTunes and iCloud which is a new .me email address. Each iPhone now is specific and each iPhone doesn't have the same user name for app purchases, each has their own unique username/password. What's the best way to go about iTunes/ iCloud with multiple devices? Each device has their own contacts that are synced/ backed up so I don't want to mess with contacts, bookmarks etc. I'm more concerned about iTunes/app purchases. What's the best way to configure multiple iPhones?
