Hi, I unlocked my iPhone 2G 2.0.1 using winpwn, and tried to use both my iPhone 3G sim card, and my T-Mobile sim card in the iPhone 2G (both which are on service plans) and none of them work on my iPhone 2G. What can I do to resolve this? All I get is zero bars and after awhile it turns into No Service. I really need my phone back. Thank you!
