Today I decided to unjailbreak my 2nd generation iPod touch. I left apps in Categories figuring it won't be a problem. I backed it up, restored, updated from the back up, and now I turn it on. I only have a few apps (the only ones I didn't have in Categories.) I figure iTunes didn't recognize Categories and didn't sync the apps that were inside Categories, but I checked in the sync list and I have about 100 apps checked off (the same ones I had before I unjailbroke.) How can I get them back?
