Here's a short tutorial on how to transfer ringtones to the Palm Pre:

  1. Connect the Palm Pre to your computer via USB Cable
  2. When the 3 buttons pop-up on the handset, select "USB Drive"
  3. A new drive will appear on your computer, open it and navigate to the audio folder, then drag & drop the ringtone into that folder
  4. On the handset, launch the "Sounds and ringtones app", select Ringtone, click add, and select the audio file you want to use as your ringtone.
