Lightwav 2 MP3 looks great. I gave it and a couple of others a good inspection. Played with them on my Treo 680 and then ran across MusicTones 1.0. It's a very simple program for importing ringtones from mp3s. It allows you to use any mp3 on your device and capture all ofit or just a brief section. It then makes that mp3 ringtone available in the Treo 680 dropdown ringtone menu.
The best part about it is it's FREE.
You can get it at
