I was wary, but works great
Being in the IT field, my family comes to me with technical issues. When my nephew came to me about getting an iPhone for his t-mobile service, I of course told him problem. After some research it looked like the ATT iPhone 4S would work on t-mobile. However, they lock it to a particular provider. After multiple unsuccessful attempts, I found keys2iphone. I was a little skeptical, but worked great and simple/inexpensive!!
