Golf Course GPS for your Blackberry

I found a program called green finder gps this weekend that turns your blackberry into a sky caddie like device. It uses the built in GPS to give you accurate distances tot he green (front, middle, back) and all hazards on the hole. The software is free to download and use 5 times. It is definetly worth trying if you don't want to drop $400 on a GPS for golf.
