Electric Pocket has released Ringo 3.0, an enhanced version of its ringtone manager for Handspring’s Treo Communicator.

According to the company, Ringo enables users to compose and share custom ringtones or download and install new ringtones from the Internet. Adding to Ringo’s recent enhancement of establishing customized ringtones for specific callers or groups of callers, Ringo will now enable users to assign photographs or graphical icons for each caller or group.

Electric Pocket claims Ringo is the first ringtone manager to bring caller-specific ringtones and pictures to the Treo, giving users options for customizing their Communicator and methods of easily identifying incoming callers.

So rather than straining to read the name on the Treo’s Caller ID feature, users can now simply associate a photograph or other graphic to each individual or to groups of callers who are classified together, such as “business,” “family,” or “friends.” When the Treo user receives a new call, the incoming caller can be identified both by a customized ringtone and their picture or some other icon.

Ringo enables Treo users to use pictures stored in the SplashPhoto format and supports full 16-bit color images. Ringo retails for $14.95 and comes with 15 cartoon icons.
