Well, it's not called the "Genius Bar" or the "iPod Bar" for nothing. At every Apple store there are people trained in Cupertino on how to fix Macs, iPods, and iPhones. Their job title is "Genius" Literally thats their job.
The forums are a way for other people to try and troubleshoot problems if they don't want to wait on the phone for AppleCare or they can't get to an Apple Store.
I understand that you are frustrated, but try bringing in your computer and your iPod. Make a reservation at
