Nine months ago, my brother and I had an AT&T family plan with no data and I upgraded to a Galaxy 3 and a data plan using my brothers upgrade (as I wasn’t eligible back then). Two weeks ago, I became eligible and so I upgraded to a Galaxy 4 (I haven’t activated the phone yet). Can I transfer the apps I purchased for my Galaxy 3 to my new Galaxy 4? Am I allowed to sell the Galaxy 3? If so, should I unlock it before I sell it? Am I allowed to sell the Galaxy 4? If so, should I activate it? (I know I am not allowed to unlock it) EDIT: Changed jailbreak to unlock.
