[myusernamename]

Is there a website or program where I can unlock my AT&T iPhone 4s on ios7.1 on t-mobile? I just want to unlock it not jailbreak it because I want to update my phone. Thanks for looking!

as far as i know If you just want to unlock you have to go via att officially. Call and ask. Simple.

You will either have to ask AT&T for an unlock or purchase an IMEI unlock for it.
