Just so this isn't a useless thread I'm going to add this in.
I had problems earlier after updating my computer to the new iTunes 8.2. My computer no longer recognized my iPhone or iPods. So the trick to get you back up and running is
- Repair disk permissions
- Shutdown computer (not restart)
- Shutdown iPhone and reboot
- Turn on Computer
- Then plug iPhone back into computer
For those that are having this problem, hope this helps and can't wait to see all of the new stuff. !!!! Downloading now
