Have botha 4gig and 8 gig still in box, just got iTunes 7.3 to install and work properly. If you were having hte -50 error, just delete all your video podcasts and that should work JUST FINE.
If anyone is in need of a 4gig before I put it on eBay, let me know. I think i want to keep the 8gig forsure now. I still have access to more 4 gig's if they are sold out in your neck of the woods.
