I have a Verizon iphone 5 and I got it from Gamestop. (Refurbished) I heard that all Verizon phones come unlocked out the box. But I haven't a clue if weather or not mine is... I really want to go to Tmobiles prepaid service but I don't know if it can be turned on at t-mobile. Can it? and are there any limitations if it can be??
