I searched on the web but i was hesitant to choose the ATT iPhone Unlock Service. When I decide to unlock my iphone, the price went up and the payment is made via Paypal so it is kind of safe with my feeling. The unlock takes 2-7 hrs. After 2 hours, I checked the unlock status, it said COMPLETED. It means my iphone is unlock, and 5 hrs later I received the official confirmation email. It is fantastic because I ordered at 1300. It is unlocked at 1500 and the official unlock email at 2100. I expect the unlock will be finished next day.
Thanks very much ATT UNLOCK SERVICE
