Most Blackberries come with a built in GPS. I think this is a great feature, but I haven’t found allot of use for yet.
One use I did find however was as a GPS tracker. This allows me to track where I go on my motorcycle tours.
First you need to get beGPS from Blackberry App World
This is the free version, there is also a paid version with a few more options.
Then get GPSBabel from here to be able to convert the data that beGPS writes.
Once you have used beGPS the first time there should be a beGPS.log file on you Blackberry SD card. Copy the beGPS.log from off your Blackberry to your PC.
Then use GPSBabel to convert the log file to a KML file like this,
or by the command prompt like this.
gpsbabel -i nmea -o kml begps.log begps.kml
Then you need to go to google maps and login with your Google account.
Go to My Maps, create a new map, and then use Import to import the KML file.
