I got a new iphone today so I gave my son my old iphone. He got it activated and it was reset. He is trying to download songs from itunes that he purchased 2 years ago on his ipod (the ipod was destroyed a year ago). He gets a message that says "this device is already associated with an apple id. You can download past purchases on this device with just one apple id every 90 days. You cannot associate this device with a different apple id for 50 days." Is there something we can do about that?
