I have a 20Gig Ipod and have had no problems untill recently. I was running the old version with no problems and once upgraded to the new 4.9 version and things didnt work. I restored back to the old version and everything was fine. So after 3 weeks of Itunes asking me to upgrade to 4.9 and with a few PodCasts I wanted to hear I needed to upgrade to the new system. So I figured I would try it again. I downloaded it and installed and it worked fine for a few days now nothing will upload to my Ipod. I plug in the Ipod and it says on Itunes that it is uploading, But it says complete I unplug the Ipod and none of the updates are on the Ipod itself. Ive done everything I can think of. INstalled th eold version but the Ipod has new version software on it so that wont work. I re-installed the new version several times and still nothing. Please someone help me, I dont know what to do and the trouble shooting guide on Apple is rediculous.
