Since I back up with rsync to my desktop and laptop, I have a copy of the DB on a machine that has db_dump. I found that "db_dump -p" gives a series of vcards encoded one per line. It wouldn't be hard to parse those further using a tool like awk or python.

Now that I think about it, Python has a Berkeley DB access library (bsddb), although I don't know if it's available for Maemo.

Jarkko, what kind of tool are you imagining? I.e., are you thinking "lookup_contact --home-phone Joe" would print out Joe's home phone number? (I'm thinking that if somebody writes a tool, it would be good to try to make it flexible so other people can use it in unanticipated ways.)
