Which software/website should I use to factory unlock my AT&T iPhone 4S? - 1
I need to unlock it to be used on T-Mobile. I want a permanent unlock and I was wondering if any of you have done it and what your suggestions are? Thanks (:

I'm buying it from a family member. I have never had AT&T, always T-Mobile.So, AT&T won't unlock it for me. I wanna know a good website that does it for $20 or under.
