I don't know how to get the ring on my phone, but it's now the sound that announces new email on my computer.
I don't know what kind of phone you have, but if you have a Motorola, you can get software from them ($30, I think) that will let you synch your phone with your computer. You will need a connector to the phone also (mine has a mini-USB cable, which I already had from my digital camera).
Once you get the Motorola software working, it's pretty easy to move your audio files between the two devices. The transfer is a piece of cake! This also means that you can record or capture virtually any WAV file and use it.
