I just recently restored my iP4 and tried to sync everything over back to the phone. Some of my music wouldn't sync. I'd get an error message saying iTunes can't find the file....anyhow, to fix that I just located the file and iTunes did the rest. The tell tale sign of this issue is when you see an ! next to the song or movie or whatever you're trying to sync. So after I found the songs they synced over fine. Now my real problem is my apps...I have about 10 apps that won't sync. I have the ! beside all ten of them. I assisted iTunes in finding the apps in MUSIC...iTUNES....MOBILE APPS. I thought everything would go smooth just like the music files. Unfortunately it didn't, and I can't figure out what the heck is wrong here. I've read all over the net this is happening to others, although I couldn't find any threads of the issue on this site. Does anyone know how to fix this problem. I'm running the most recent version of iTunes.... on ios 4.1 on a iP4 Suggestions? Did this same thing happen to you? If so, how did you fix the problem?? Thanks in advance everyone!
