I have the same problem as well... This only started hapening when i upgraded 10 .109. I have a feeling it might be the OS. I have it in my music folder and ringtone folder but it doesnt show in the ringtone folder. Also before on .75 I was able to choose a song and make it into a ringtone (not just set as a ringtone) Now with .109 that feature is no longer available.
