I've had success with the Test port. (for me it's COM4) [aka SAMSUNG CDMA MODEM DIAGNOSTIC SERIAL PORT (WDM)(COM4)] 4. Click the FileSystem Tab, it looks says 'Filesystem' and is the 2nd to last one on the right. After loading a bit you should see your phone's file structure. 5.

It will then start sending the file to your cellphone. 11.Another important step, restart your phone before attempting to view it on the phone or it won't show up in the GIN menu under Tunes And Tones. 12.Now you may set it as Ringtone, Alert Tone, or Ringer ID. EDIT: TO DELETE A RINGTONE Do it through GIN > Get Tunes & Tones > Left Softkey is 'Erase'.
