I've got a WAV ringtone on my Treo 600 that only plays once during a call. Does anyone know if there is a simple freeware app that can make the WAV repeate over and over until I answer the call? It looks like MIDI files repeat automatically, but I guess WAVs do not.

LightWav looks like it may provide the functionality I need, but I'd want to be sure it worked before purchasing it; plus, I don't really need any of the other LightWav features.
