So, I'm syncing my iPod with some new music from a couple CDs, and in the middle of the sync, it starts to say "Removing [insert app here]" When I saw it, I immediately hit cancel, just in case... But the damage was done, many of my apps are totally gone. Not even the old backed up versions are able to be found. I assume I can re-download them since they'll be in my purchase history, but is there any way to get the back up files back?? Help!
