So I don't understand or know much about unlocks but if I call AT&T to unlock my new 5 (read a few reports of them doing so) will it still be being used on my AT&T contract or does unlocking it mess with that? And will I be able to use it on another network such as Verizon if I ever leave AT&T? (Or eventually sell it haha)
Att will only unlock it if you fulfilled your 2 year agreement or paid an ETF. Unlocking just lets you use your phone on any gsm carrier in the world. No you will not be able to use it on Verizon be cause they use CDMA.
