I have a jailbroken iphone 2G, which has worked like a dream from day 1. The screen became unresponsive so naturally I tried the usual reboot, and reset (home button and on/off button) and this didn't solve the problem. I then connected the iphone to my mac, and tried a software reset from iTunes. iTunes tells me that I need to enter the 4-digit passcode to unlock the phone prior to resetting, however I can't do this because the screen is unresponsive... So I'm trapped. Is there any way out of this? I'd appreciate any help..
