Skype

you can already do that with the 3g...

Just download the Skype app, and off you go

 

You can only talk at the moment, but if Apple has been kind enough to put the front cam in the API, I'm sure the Skype developers will include video calling in the next update

 

nope

sorry.

 

Probably not any time soon, however if someone jailbreaks the new ipod touch you can download an app on cydia called movicha, it supports video calls to desktop if they download a program for it, its not perfect but its the only app that does it at the moment.

 

for f!!k sake, its running iOS 4, the as iphone thus it should work without any problems.

To the person who considered Skype slow, they are not.
