Today I called AT&T and ask them to unlock my and my gf's iphones but they refused as I don't have AT&T account... and I am stuck with 2 useless iPhones, anyone know what can I do ? There are both iPhone4 so I can't unlock them using Cydia. Maybe anyone can help me ? Call AT&T and ask them for unlock? I will provide IMEI for you and send you some $ via PayPal ? Please PM if it is possible.
