Any way to tweak GPS settings?

[BooDaddy]

I have been noticing that the GPS is kind of Janky on the TP. I have tried Mobile XT and Google Maps, and the GPS seems to be "jerky" and only updating the position every few hundred feet.

While in the car traveling 60mph, it will sometimes lag behind the actual streets as I pass them. Again, this happens in both XT and Google maps.

Whats worse is when your walking. Its almost as if the gps stops reporting position when you are walking, and you have to walk several yards before it will update the position. This is horrible when you are trying to Geocache with the phone.

Is there any tweaks we can do to make the GPS resolution a little better?
Im runnin a stock Sprint rom BTW.
