iPhone restore error 1604
Problem is that I’ve tried to restore about 30 times and each time it fails while "preparing the iPhone for restore", typically with error 1604. I don’t see anything on the Apple web site about this error, but I’ve tried every troubleshooting step I could to get the restore to work: uninstall/reinstall iTunes and the other Apple components, stopping and restarting the Apple Mobile Service, rebooting, trying different USB ports, etc. Nothing works. And the battery doesn't charge either.
One thing of note: I'm using an iPod cable... would that make a difference? The salesperson at the Apple store said they are interchangeable, so I brought one cable for both the iPhone and the iPod.
Please help! I’ll be in China another week and a half and am phoneless. What is error 1604 during iPhone restore and how do I fix it?
