Wifi Diagnostics (Advanced)

The "Serving UNC Address" and "Security Gateway Address" fields start with my lat/long location. For some reason I've looked at these dozens of times but never realized it was my lat/long. Does this have to do with what you fill in for your e911 information? Or does it just know where you are when you switch from EDGE to UMA? It says nXX.w121.t-mobilesgws.com and nXX.wXXX.t-mobileuncs.com:140001

Well on EDGE it can triangulate your position..
