I have upgraded my iphone 2g to 3.0. It worked fine for a week or so. Suddenly the phone, bluetooth and wifi are not working. A message pops up on my screen saying that iphone need a restore. When I try to restore it, its getting stuck. I even tried it in DFU mode. I tried to re-jailbreak, it got stuck at the baseband flashing screen. Do any one have any idea what to do?
