Tom Keating uncovered a new release of the app Talkonaut, which was originally designed as a J2ME application that provided VoIP calling and multi-network IM capabilities. Now they have added a new native Symbian app that works on a number of Nokia handsets.

I did see a couple of interesting features, the most interesting one being that the application will run over a WAP or limited GPRS connection. Calls that touch the PSTN, either because you use a non-VoIP capable handset or because you are calling a PSTN number, the call will go through the GTalk-to-VoIP service.

I'm having a hard time trying to figure out how this solves a problem differently than Gizmo5, EQO, or any number of other services. Anyone try this application care to comment?
