Hello, I have an Iphone 3G which I got from England and unlocked it. Recently I updated it to 4.0.1 and everything was fine. Then I updated it to 4.2.1 and ever since it has been in recovery. I have tried almost everything. Recboot, Tiny Umbrella, redsnow, still nothing. irecovery doesn't recognize the device. I have tried restoring it using DFU still no luck. Any help would be much appreciated!
