Today sees Windows 7 go live and available, and the guys over at the iphone blog have set up a forum to deliver help to those who require it when upgrading to Windows 7 and transferring your iPhone over from Windows XP.
The thread starter, Rene Ritchie, starts off by giving his practices for getting everyone started and goes like this…de-authorise you old machine via iTunes, copy all iTunes media to a suitable USB drive, only iPhone / iTunes , install Windows 7, install iTunes, authorise new machine in iTunes, copy iTunes content from USB back to Windows 7, restart iTunes, and then sync the iPhone.
Another poster mentions to make sure you grab the iPhone back up files. So there it is, hit up the link if you need help with the iPhone and Windows 7.
