How do I go about installing the $9.95 software upgrade? I already upgraded my actual iPod touch to 2.0 and then today just purchased the update. It said I would need to plug my ipod in and hit install or something so I hit "Ok" on that screen and it dropped me back to my library, I plugged my iPod in it synced and nothing else happened. It didn't sync the update though, what should I do?
