I have a problem. My iPhone 3G refuses to reconnect to the Cell network after being in an off-area where it did have no service. If I leave that No Service area, the iPhone does not reconnect and stays on No Service. My family and I are in Europe right now an therefore my iPhone is roaming on their networks. When I have the problem, that my iPhone does not reconnect and I go to the settings menu and go into the carrier selection, it gives me 3 different networks, but if I select one of them it says that it is restricted. The only thing I can do to get service back is reboot the phone, airplane mode on-off does not help. I also have that problem when I am in America and not roaming. It happens regardless of 3G on/off and Data roaming on/off. I have 3.0 installed, but it also happened on 2.2.1. Can you help?
