Hello, I've just jailbroken and unlocked my iPhone 3g, upgrading it with redsn0w to iOS 4.2. I've followed all the steps using a PC with Vista, but it hasn't worked, I keep getting 'no service'. And when I go into Settings --> Carrier - it says 'Unable to load network list'. I've read other forums and tried all their advice, but they didn't work, and also, most of them were from 2007! I've read on some forums that OI've updated my Modem Firmware too high or something? Any suggestions? Thanks!
