Really need help, people. I have a 2G, First Gen, 16gig iPhone, that was unlocked and jailbroken by me via ZiPhone with 1.1.4 firmware some months ago. Installed a bunch of beautiful apps, used it with T-Mobile without a hitch, that is until I decided that it's time to upgrade to 2.X.X. Downloaded PwnageTool after updating iTunes to 8.0.2, followed all the steps in the instructions... and the phone is now locked with the: "The SIM card inserted in this iPhone does not appear to be supported" message. I would be perfectly happy to go back to 1.1.4 thru ZiPhone, but have already tried that to no avail. So I don't even have a phone now. Any help would be greatly appreciated.
