title: Preventing Cheaters: Is it really a mobile device, or is an emulator?
body: <p>I'm developing an application on both the android and iPhone simultaneously.  Due to the nature of my geolocation application, it's important that the information is <em>really</em> coming from a phone, and not just an emulator that happens to have the application installed.</p>
  
  <p>Is there some kind of value I can pull from the device(s) to determine if its an emulator?  I don't want users cheating the system by simply setting their own values for their lat/long coordinates.  I know nothing is fool proof, but I would at least like eliminate as much fraud as possible.</p>
  
  <p>I plan to have algorithms in place to validate data being recieved, such as jumping n. miles in n. seconds from your last location -- but this could cause false positives in some situations -- especially on some Androids, where you can magically be placed all over the world moving 2 feet.</p>
  
  <p>This is applicable to both the Android and iOS.  Answers for either phone would be fine.</p>
