YAY, i figured it out. Just renaming the mp3's to .mid without doing any kind of coverting, The mid works fine with ringtones. I transfered them using my MicroSD card for it. Not sure if it works with any other method of transfer but the SD card works great.
Also just in case this is helpful to anyone, i try'd using my headset from my original xbox(xbox live) and it works great for a handsfree until i get a working bluetooth. Some bluetooth devices seem to have complications with the a930.
