I don't know what the problem is with 3G video call. Can anybody clarify it?

I am currently trying to use GTalk. It was rumoured to have audio and video calls, so could be a good Skype alternative for those who do not like Microsoft's ownership of Skype.

For the future, I would think about XMPP-Jabber whatever. But these times, everybody has to have a GMail account - even if it is not actively used - so GTalk is easier to switch to.

Thank you. Best wishes.
