Hey guys, I recently jailbroke my 8GB iPhone 3G (2.21). I used PwnageTool on 10.5.6 and restored. Everything went fine and there were no errors or anything. However, I have no service now. The last bar on the left shows like half a bar but there is no service. I have At&t and didn't hacktivate or anything. I've jailbroke my iPhone twice, and both times the exact same thing happened. I have jailbreaking experience, having done it several times on my 1st Gen iPod Touch. Please help! In this modern world it's tough to survive with no communication. Thanks a lot in advance! What I did to try to fix the issue: 1. Restore again. 2. Sync again (from my non JB profile). 3. Restart the phone. 4. Reset the network settings. 5. Reinsert the SIM card. Thanks again! Remember, I already know that this issue was caused by jailbreaking because I haven't had a single At&t related issue while non JB.
