I just got an ipod touch for christmas. I've got it all synced to my computer, but the 2.2 update doesn't show up! The ipod is already running version 2.1.1. When I go into iTunes and press update it tells me I'm already on the newest version, but I'm not, it says 2.1.1, not 2.2. How do I go about getting the 2.2. update to appear?
