i'm buying a 3 and giving my 2 to my son. it has some very good paid4 apps on it, but he wants to have his own apple id.
whats happens if he changes the id on the 2? i know he will no longer be able to sync to itunes withthe id currently on the 2.
can he still use the paid4 apps on that 2?
if he syncs to his new apple id will that disable the paid4 apps?
can he back those paid4 apps to HIS OWN cloud account, change the apple id, and sync the cloud apps back onto his ipad2?
etc etc? what will be the ramifications of changing the 2's apple id?
