is there a census on this yet? i know alot of people like telenav, but i am referring to the free ones. i already have a tomtom and i was just curious as to what is the best match software that is free.

You mean consensus? No. There are many preferences among the free apps.

This guide seems to be nearly complete:

BlackBerry and GPS

I found Telenav to be slow and like Mapquest Navigator the best.

That guide is quite comprehensive, but is over a year old and doesn't include many recent updates to the products or newer BBs.
