Banshee won't keep ratings and playlists on ipod nano 3g

I worked for hours rating about 300 tracks and setting up several playlists and it looked like everything was good but after I disconnected NONE of it was saved in the ipod! iTunes was the only reason keeping me in windows environment and I really don’t want to go back! I tried searching forum first but found nothing with my exact problem. I am running opensuse 11.4 x64 w/ banshee 1.9.3 Any ideas?
