We have just released OctroTalk 2.0 - this version has real time video conferencing, along with all the old goodies like voip, file transfer, IM. It also has Avatar support.
Please check it out at
http://www.octro.com/. If you would like to download it directly to your Pocket PC, you can do that from
http://ota.octro.com/ppc/octrotalk.cab
Unfortunately though, front camera support is only for Samsung blackjack - since HTC hasn't opened up their API to access it.
Please send us your feedback at
