For some reason, I am unable to update or restore my iPhone 4 or my spare 3GS to 4.0.1. I keep getting this error message after it goes through the "Extracting Software" and "Backing Up iPhone" steps: Does anyone know how to get past this? The iPhone servers shouldn't be busy, and it was saying this a couple days ago, too. I've tried restarting the computer, hard rebooting the 3GS, switching the USB cable to a different port, switching to a different cable, and restarting my router, but nothing seems to be working. I can connect to the iTunes store just fine, and it does this both on my account and another account. This is frustrating. Any ideas?
