Recently, I went on to iTunes and it said my latest version was 1.0.2, so I tried to update it, it said it was the latest version. I downloaded the 1.1.1 Firmware and did the shift-click, it gave me an error. I re-installed iTunes, and restarted my computer. Any ideas? I didn't install any new apps or anything, it just was like that when I went to iTunes. Now some of my apps don't work.
