Messenger for Symbian S60 mobile phones?

Hello everyone!

In Finland we say that "The hunger grows when you eat". In my case
this will now happen with my possibilities to use my Nokia 6670 mobile
phone for different things.

Now I am interrested in if there exists a Messenger application (for
..net passport use) to be used directly in the phone through a
GPRS-Internet-connection? It will be nice to sit somewhere and chat
with other .net passport users with the phone only, without carrying
the "heavy" laptop everywhere.
