I spilled a small amount of water on my iPod, and it froze up. I tried to reset it, but it kept giving me the "sad iPod" icon. I charged it a little bit, and I was able to get it into disk mode. Now that it's in disk mode, is there a way to get it back into iPod mode? I really don't want to do a restore because I'll lose a LOT of music that I no longer have on iTunes. My dumb *** didn't make a backup before deleting some songs...
