zdanee: ah, still wouldnt solve my problem. I already can easily find out which version in on which repo. Like i said, i want to know which repo my installed app was downloaded from. :-) Would be nice to be able to list all installed apps with something in front of each name saying "Repository you got it from: extras/testing/devel"

misterc: hehe, have my n900 since 2009 and its been a wonderful experience in both mobile and linux land. well, but n900 doesnt have those interfaces. :-)

Thank you all for the feedback. Though i still havent found how to do it, i havent given up on it.
