I just jailbroke my phone using the Pwnage tool. After restore, I have no connection to the ATT network, and all calls are immediatey listed as "call failed". Can anyone help me restore my network connection so calls can be made. Thanks
You'll most likely have to re-jailbreak, as this is the only the fix in this situation. When using PwnageTool, be sure not to check "Activate Phone" if you are using Expert Mode, if if using Simple Mode, tell PwnageTool that you are a legit AT&T customer.
