MP3 TONES READ THIS WORKS!
I never could find ne thing on here that would work for my G/F's A890. Well I came across this site. http://members.dslextreme.com/users/samsung_a 890/
It works bottom line. They sound just like my VX8100 MP3 ringtones I made.
It takes a little bit more time but they sound so much better then just using a QCP converter.
Just click on ringtones and follow Creating Ringtones for your Samsung A890. Its easy theres even screen shots!
