Well, according to my carrier (Rogers), RIM's answer is....... Bluetooth GPS is not supported! And it's not just my BT359, but any Bluetooth GPS with the blackberry is not supported. So I say it's not my GPS's problem, he tells me he told RIM that, and that I had verified the innacuracy by using two other services. RIM's answer, not supported. My opinion of RIM just went down significantly.
