How accurate is the GPS tracking?

How accurate is the Accutracking service on Nextel? i.e. accurate to how many meters?

Also, any plans to incorporate SprintPCS soon? They seem to have location based services in their SDK.

GPS accurary from Garmin (http://www.garmin.com/aboutGPS/waas.html):

100 meters: Accuracy of the original GPS system, which was subject to accuracy degradation under the government-imposed Selective Availability (SA) program.
15 meters: Typical GPS position accuracy without SA.
3-5 meters: Typical differential GPS (DGPS) position accuracy.
< 3 meters: Typical WAAS position accuracy.

iDEN cell phone GPS is within the range of 2nd level +-15 meters (+-50 feet).

Any link for the SprintPCS phone and SDK?
