title: Adobe Air - Detect if connection is WIFI, 3G, or EDGE
body: <p>I need to determine which connection type a device is using. 
  Distinguishing between WIFI and 3G doesn't seem to be a problem on iOS (using the <a href="http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/networkinfo.html">NetworkInfo ANE</a>) and Android (using the native NetworkInfo class) but I've got no clue how to further distinguish between a fast (3G, 4G) and slow (EDGE) connection.
  Is there a way to do this with Adobe Air?</p>
