Iphone won't sync anymore, to any pc.
I have this first gen iphone. It has a huge problem. It does not sync anymore or anything. I have tried 3 different pcs and 2 different cables, and nada. Each time I plug it in it says usb device not recognized. Even if I put it in DFU mode it still says usb device not recognized and comes up as unknown device in device manager. Is this a software problem? If I can't connect to the pc how am I supposed to restore my iphone?
Thanks.
I'm a PC, Other OS, Win7 FTW--Macs are cool too.
