Alright, my dad and I both have new 3GS's, they worked just fine. I updated iTunes and iPhone OS 3.1.3 and I'm going great. He did the same thing, but his iPhone won't sync properly. He sync'd his music and podcasts to it first, and then was syncing apps and soon as he clicked Apply all the 3rd party apps he had set to get sync'd to his iPhone just disappeared and left only the Apple apps on there. It shows only like 16.9GB available, on his 32GB iPhone 3GS when I check "About" under General in Settings, but it says there are no songs, podcasts (no movies or anything else either), and only one photo. Anyone have any idea what's wrong? EDIT: it keeps saying that he's not authorised to sync this content, he's tried going to Store > Authorise Computer and it just says "We could not complete your iTunes store request. An unknown error occurred (-42408). There was an error in the iTunes store. Please try again later.
