My iPhone 4 won't restore fully. I've got 4.1 downloaded through iTunes, and I'm using the latest iTunes on Windows 7 x64. I have tried 4 times now, rebooting, using different cables, etc. It stops at about what appears to be 65% and just sits there. I've left it for 10, 20, 30 minutes, and nothing. No errors on the phone, or in iTunes. Any ideas?
