The Treo 600 plays great ringtones, and Ringo makes it easy to organize your tones collection, and adds ground-breaking support for adding new tones...
Ringo lists all the ringtones on your Treo, and lets you rename them to your own taste or delete the ones you never use. The Treo 600 supports industry-standard polyphonic ringtones in MIDI format, which you can e-mail or download to your Treo 600 via Blazer. Ringo provides a built-in link to a Treo 600 optimised ringtones store, which you can browse and shop with your smartphone.
The software provides an easy way to set and change ringtones for your friends. Each friend you set up can have a unique ring and SMS tone, and their picture shown on screen when they call. Ringo lets you quickly and easily set a unique ringtone and picture for each category in your Treo's Address Book.
