For all of those people who show their location off. Can anyone verify that the location showing on the device is actualy a CELL TOWER. My point is that the location shown is actualy the tower that your blackberry is using.

So if this is true. Then there is no triangulation going on. Just cell tower location. If this was true triangulation then the accuracy would be better. Also for triangulation to work your blackberry would have to be talking to 3 towers at the same time. So it can cris-cross your location. In the current setup it only knows what tower your bb is talking to.

So if you are in the boonies your bb should show you a less accurate location because those towers usually have a longer/larger coverage vs. a city cell tower which are lower and more numerous thus closer to your acctual location.
