I just got a 4s, and my wife inherited my 4. It was synced two days ago on my account, and still has all my apps (very few) and settings. (Her phone numbers from her Crackberry were ported over by AT&T, and the phone is up & running on her number. My wife is NOT technical, & does not yet have an iTunes acct. What will happen if she does nothing? What will happen if she gets iTunes acct?
