    downloaded and tried to install 4.0.1 on my iP4, but update didn't finish and my phone is now in recovery mode. It will not restore from a backup or from 4.0. I keep getting an error code 9 that seems to involve the USB. I've tried restarting everything, tried another cable and USB port. Any ideas?
