I was finally able to upgrade my 3GS to iOS 5 but now I'm having trouble syncing my music. The info shows up in the iPhone music folder in iTunes but its greyed out with a little syncing symbol. It shows the space being used up and the files totaled at the bottom but there is no file on the actual phone. I've tried both wired and wireless syncing without success. It syncs some tracks i've ripped but not all.
