I'm sorry for the confusion! An AT&T iPhone (first-generation, 3G, 3GS, 4, 4S) cannot be unlocked when bought from the AT&T store, 3rd-party reseller or from Apple as an AT&T model...this is because in the United States, carriers are not required to unlock devices for use on other mobile networks, so, to trap us with their network, they require that the device, in this case the iPhone, be required to operate on their network exclusively. AT&T and Apple, due to policy and United States law, will not unlock your iPhone, and I'm really sorry about that. Their are third-party ways to unlock your iPhone, that cannot be discussed here, but they will void your Apple warranty, and could potentially damage your device. Also, be aware that warranty service...for any iPhone...will only be handled in the country that the iPhone was purchased in...so if you have any issues with your AT&T iPhone, or United States; factory-unlocked iPhone...you'll need to contact the United States Apple division for support.
