I had a previously jailbroken (with PwnageTool) iPhone 3G with a contract through AT&T. Today I jailbroke it again with PwnageTool 3.1.4. I unchecked Activate phone and didnt go into DFU mode since it was already jailbroken. Everything seems great, it works, I made a phone call on it but next to my signal strength, it does NOT indicate my network (doesnt say AT&T, E, or 3G). When I go to settings >General >About ... next to Network it says "Not Available." Whats up? Can I fix this???
