What I do is use Audacity(free software) to create the ringer from an actual mp3 file. It allowa you to choose the 23 seconds you would like to use as a ringer, and place effects in as well such as fade in at the beggining and fade out at the end and also amplify the ringetone file then I transfer that new 23 second mp3 file to the memory card. Now you'll need another free program called Minitones that actually installs on the Centro or whatever Treo you are using. Now the Minitones application allows you to trim an entire mp3 on the device, but for me that is to hard to figure out exactly what section I want to trim thats why I use Audacity to trim it on my PC first. Now just open minitones on the Palm and choose add then put a check in the box next to the file you want to use as a ringer and viola it will put that mp3 file in the sounds section of the device and now you have the ringer you want without any out of pocket expense !!!!!!!!!!!!!!
