Top Rated Playlist Missing Iphone 3gs?

My Top Rated List from my Iphone 3gs has disappeared recently.

I understand people have un-sync'd everything and then sync'd again which has worked for them.

I have quite a number of songs deselected that i had to do manually and took me a while so i do not want to do this again. I love my top rated play list though.

Is there another way to get it back?
