Before I updated, as a precaution, I saved the folder /var/moblie/Applications onto my computer. I restored my iPod and lost all of my apps. They are not on iTunes for some reason, and when I copy the Applications folder from my 2.2.1 iPod into my 3.0 iPod, they don't work. Any help?? --I did take the .dat save files and put them in a re-downloaded app and it worked. However I had about 1.5 gigs of apps and slow internet, so downloading them all again isn't much of an option.
