For those of you who have a BB that has GPS capability and do Geocaching I have come across an app that is really cool.
My wife and I each have BB Curve 8310s. We enjoy Geocaching and up until a few weeks ago used a Garmin GPSR. Some Geocaching buddies mentioned GEOCACHING NAVIGATOR and we thought we would give it a try. We got it from a link on the GeoCaching.com site.
We have found that it is a great app for this purpose and it is more accurate in precision GPS coordinates than our Garmin GPSR. It will put you right on the published coordinates for a cache with a function called Radar.
