I recently signed up for the AT&T Next Program. I was on the Apple Upgrade Program before. With the AT&T Next ( I have the one where you can upgrade every year, or once half the phone is paid), can you get AppleCare to put on that phone? Once you trade it in for an upgrade (assuming its still Apple of course) can your AppleCare transfer to that phone? Do you have to buy new AppleCare with each phone?
