I recently updated my iphone to 3.0.1 and Installed Winterbord and I had to reboot and after that it never booted up... It's just an endless cycle of Apple Logo Black Screen And apple Logo With rotation Load Icon and then back to Apple Logo and so on... I tried to restore on 2 different Computers and Itunes but it always crashes or says Invalid response received from Iphone... Please help this is a 2g if that makes a difference....
