I'm looking for gps tracking software and yes I know there are a bunch of them available for the blackberry, but I am looking for something specific.

See I'm not looking to share my location with the world. I am looking for something that will record a "track," a GPX File that I can then get off of my blackberry later.

I am a photographer and I want to use this for geotagging my photos.

Since I always have my blackberry with me, if I could get something to record my track, I could then munge this data with my photos matching time stamps on the photos to the time stamps on the "track" to geotag the photos.

I am sure most of the gps tracking software out there does this internally, but does anyone know of one that lets you save the track as a gpx (or xml) file?

bbtracker has already been mentioned. You also might take a look at MobileTracker 1.4. It will save to either GPX or KMZ.
