Hi folks, please accept me to your great forum. I am in the UK I have a 2nd hand 2g iPhone on the AT&T network, i done a factory reset and it obviously requires activating again, i bought a 2nd had sim of off a auction site and it has gone through the process to activate however it requires a valid zip code and SSN, these i dont have obviously being in the uk. However i have trawled through various websites to unlock the said phone to accept a uk sim, i CANNOT make any sense of it, i have tried and downloaded various programs and software to supposedly unlock it. Does anyone please have an complete idiots guide including direct links for required programs, the phone is on 3.1.3 at the moment. Kindest regards in advance.
