Somebody pointed me to GeoJabber before; I'm not sure if I can try it, I dont see if it runs on my 770/OS2006. Doesnt say anything about requirements.

The point would be though to implement JEP-0080 in the tablets built-in IM client at least in OS2008. It would make both GPS and IM more useful even for new users who dont want to try installing 0.0.1-versions of software.

(OK, I'm assuming it's not built into the client; maybe it is after all? Hello, N810 users?)
