All files vanished..

But still show as there in itunes? It still lists all of my data for music/movies/apps etc, even after turning it off and on.. But I can't view anything when I go to iPod on the phone...

Any advice?

When did you do this. I've had times where a sync took a few minutes after opening the iPod to show the music. Look at the About screen in Settings>General. If it's still not there, resync.

When you open iTunes and select your iPhone on the left, does it show a color-coded breakdown of the media you have synced over?

What is displayed when you open the iPod app on your phone?
