Hi, a bunch of my favorite apps don't work with iOS 4.0 and I was looking for any OS4-compatible replacements/similar apps that might be out there? Video Downloaders -- I used MxTube, aTube, and YourTube. None of these work anymore. "Finder" -- I used iFile to look into my iPod's file directories, and now it doesn't work (unless you change the system date, which I don't want to do.) First-person shooters (legit App Store) -- I used Modern Combat and Brothers in Arms 2. Replacements/similar apps for any of these?
