I have a bunch of custom ringtones in mp3 format on my sd card. When I attach a file and pic to send as mms in handscent they are all alphabetical but in 2 sections. i'll scroll down through a-z, then after that it starts a-z again with other rigntones. They are all stored in same folder. Why is there 2 sections of ringtones instead of just all in one a-z list?
