VNC program that works over 3G?

Try mocha VNC lite. Also, it looks like PearPad has a lite version but I don't know anything about that.

My jaadu works on 3G. You probably dont have your router setup to forward the ports properly. Dont forget wifi is your current network (usually) so the traffic never leaves your router. If you are on 3G, the phone goes out to AT&T and tries to come back in. If its not forwarded, it wont work.

But yes, Jaadu works brilliantly on 3G.

Jaadu works for me over 3G. I use it to connect to 3 different machines, all working just fine.

I use Mocha lite over 3G, and its free. Jaadu is damn expensive, but it looks way better. I want to try Jaadu, but 20 bucks.

I use Mocha VNC Lite. I may pony up for a paid version since it adds some more functionality in the interface.
