The iPhone 3GS was still syncing and backing up on the Win 7 laptop. It would sync but not backup on the Win 7 PC.

I uninstalled everything with an Apple name, including QuickTime and Safari.
Installed all the programs again and had the same problems on the PC. Would not backup.

About an hour later, my iPhone 4 arrived.
I plugged it in and went thru the setup with no problems. I set the sync folders and hit the button; it synced and backed up in about one minute.

Of course I lost all my Notes and settings since there weren?t any previous backups from the 3GS on the PC.

After about two hours of applying new settings, email and notes, all is well.

It?s a great phone!
