title: How to detect if the iPhone is using Wifi GPS, or their default wifi loation?
body: <p>When the iPhone can't find a GPS signal, it uses Wifi to guess at your GPS location.</p>
  
  <p>When it can't find your Wifi location, it defaults to the wifi network where you activated your phone.</p>
  
  <p>Is there any way to determine when these two forms of location are occurring?</p>
  
  <p>The LocationManager provides a horizontalAccuracy reading, but if you are using your home Wifi, it says (rather inaccurately) that it has a +/-500 range, even if you are miles away.</p>
  
  <p>Also, is it posible to know how many satellites the phone is reading?</p>
