I am a current month to monther on att and have an unlocked 4s. Was planning on getting a 5 tomorrow but wondering what the best deal is. If i buy an uncommitted att phone at apple store is that unlocked if i want to travel abroad or is there something special i have to do for that? Someone mentioned buying dirctly fromm att with contract then canceling. Phone +cancellation fee gives better price but then can i unlock the phone myself?
