Is it simply powering up to the apple screen then turning off?
It was stuck in a reboot cycle, so I opened iTunes and tried to restore. iPhone just hangs at the progress bar - doesnt switch off or anything. iTunes says waiting for iphone. If i unplug it, I get iTunes error 9
My iPhone simply wont boot?
