Is there a way to manipulate GPS data?

[ah33919]

Is there a way to manipulate GPS data on a 6800? I would like to be able to either manually input or store (freeze) coordinates and somehow disable the phones ability to update its GPS location rather than just turning the GPS function off. I know that when using Sprints tracking software they also have the ability to triangulate your location using cell towers but if the phones GPS is actually transmitting stored (bogus) or preset data wouldn't that eliminate the "need" for triangulation because of the lack of GPS data? Thanks in advance.
