Samsung UpStage M620

Just as an added note, once you have converted the ringtone to a .3g2, you have to match the file name to the preselected names that the phone uses when it creates a new file, for example, SSPX0015.3g2. (I think that the SSPX is the important part.) Also, when you add the file to your memory card, you have to move it into the phone's memory before you can assign it as a ringtone. Go to TOOLS-MASS STORAGE-MEMORY CARD, select the ring tone. Under options, choose MOVE. It will give you the option of moving it to TOP DIRECTORY or ALBUM. Choose album. Now you can go into SOUNDS-RINGER and assign the ringtone!
