With Sonic Boom's ToneMaker users can create their own music by layering their own vocals on prerecorded tunes. You can then use the clips as a ringtone or pass them on to others. ToneMaker is $3.99 per month on handsets with Verizon's Get It Now Internet service.
YouTones from FunMobility takes the same concept in a slightly different direction. Users can combine their own voices with a selection of prerecorded thematic YouTones performances to use as ringtones or audio messages. Also available on Get It Now phones, YouTones charges $2.49 for each created clip.
The last application is mSpot's Make-Ur-Tones. With this application you can create customized ringtones from a catalog of over 250,000 music tracks. Users select a 30-second audio clip of their chosen song before downloading the new ringtone to their phone. Ringtones are $2.49 each.
