Hi everybody
Yesterday i just unlocked my iPhone using PACAY method and it seemed that the iPhone unlocked correctly, then I put my Cingular sim card and try to make a call and it works flawlessly. But when i give the phone to my friend and used his T-Mobile sim card, the "No service" 's appeared. I try to restore but the problem still stays here.

Any solution for this problem ? Pls leave your comments. It's so weird with me
