title: how to increase GPS polling rate on Windows Phone 7
body: <p>Is there any way to increase the gps polling rate in my WP7 app?  Right now its updated roughly once a second.  I need at least three or four times as much resolution..  </p>
  
  <p>I was considering spawning multiple GeoCoordinateWatcher(s), each in their own thread, but that doesn't sound like it would work.</p>
  
  <p>** a bit of background **
  I'm trying to measure 0-60 with my application, but am quickly realizing when testing with cars that do sub 5 second 0-60 runs (GTR, ZR1, 911 turbo, etc), sampling once a second isn't going to give me an accurate result. </p>
  
  <p>It sounds like I have to rely on the accelerometer to get this data and use the GPS data to correlate?</p>
