Cross Platform (WM/WinXP) VOIP apps that work on Titans?

[faustt]

Anyone know of an app THAT WORKS WITH THE TITAN thats similar to Skype? I've using No2s newest 6.1 rom, so Skype is out. I also tried to use Skype via Fring, but the mic doesn't pick up anything.

My needs are pretty simple:
Run on PPC correctly (Titan) and also have a windows based client
Work with a bluetooth headset
Perferabbly be able to run off of RevA or EVDO. Wifi only would be a step in the right direction though.

I can't seem to find anything that works right with the Titan. Do the WM versions of Yahoo/AIM/MSN have a voice feature that could work with the titan? I've always used Slick, so I've never tried them out. I'd really rather not downgrade to a 6.0 rom and deal with another hard reset. But if 6.1 is just that buggy with these apps...
