My PC had stop detecting my iphone. It is on 1.1.3. Couple of weeks back when i tried to plug to my PC to charge my iphone on USB, the iphone charging indicator does not show and my PC does not detect it at all. I tried launching the itunes but no iphone is found in there....If i leave the cable intact for long enought and i remove it and reboot the iphone, the battery indicator will show full bar. Does anyone out there know what could be the problem??? Without the PC detecting it, i cannot upgrade to 2.o firmware.....
