Tones sync

Guys, hello! I'm new on "i" world and I just bought my first i-gadget, the new iPad. Well, I don't know if this is an issue just of the 3rd gen, but actually I can sync music (mp3), video and apps with my iPad via iTunes... BUT when I try to sync ringtones/tones (I've found a good mario bros one *--*), iTunes just shows up a forever-syncing-icon (image below) and I never find the "uploaded" tone at Settings > Geral > Sounds =////... Am I doing something wrong or what? I appreciate your help! Thank you!

***the tones I tried are in .m4r format

 

found what was wrong.. It appears that iDevices doesn't support manually transfers of Tones (just of tones, because musics and videos were working fine to me). So I had to check the automatically sync mode, and it's working now. Thank you
