Im very confused about the iphone 5 being locked or unlocked. Basically heres what i want to do but im not sure if its possible. I live in mexico where the iphone 5 isnt available for sale yet, my brother lives in houston Tx near an apple store. Can he go, buy the full price iphone 5 32g with no contract, and will it be ready to work with my telcel card that i will cut? Or will he need to be an att or verizon costumer already?
