Unless you have a Verizon 8830, then they've disable GPS, so that they can sell you their VX Navigator product.  However, the latest version of Google Maps latest version has somehow figured out how to access the GPS device.  To download, go to: http://google.com/gmm from your blackberry's web browser.
