Hi, I am currently using iPhone 4S (16GB) model, and I am trying to get an unlock so I can use it on international use (such as in Korea like WCDMA and etc) I am pretty sure I am qualified for the unlock requirement, but I am not sure how to unlock my phone. If anyone know how to unlock verizon iPhone 4S, please leave a reply. Thanks! p.s. after unlocking, does it lock by itself when it approaches certain amount of time?
