upload ringtones that you create to your fone either by usb cable, bluetooth, or memory card slot
mp3 ringtones in the svdsound folder can be assigned to any person in your contact list
however, in most cases you need to rename the mp3 extension to mid to set the ringtone as default.
this is covered in several threads throughout the kyocera forum, many times I have made the the post
its really simple
the person you spoke too doesnt know anything
