title: network connection status from PhoneGap does not update in Ripple
body: <p>The standard PhoneGap API for checking the current network connection (see below) does not seem to update it's result in Ripple Emulator. When I change connection type and execute checkConnection(), it returns the connection type from the first call to this function (at deviceready)</p>
  
  <pre><code>function checkConnection() {    // Checks current network status
      networkState = navigator.connection.type;
      console.log(networkState);
  
      var states = {};
      states[Connection.UNKNOWN]  = 'Unknown connection';
      states[Connection.ETHERNET] = 'Ethernet connection';
      states[Connection.WIFI]     = 'WiFi connection';
      states[Connection.CELL_2G]  = 'Cell 2G connection';
      states[Connection.CELL_3G]  = 'Cell 3G connection';
      states[Connection.CELL_4G]  = 'Cell 4G connection';
      states[Connection.NONE]     = 'No network connection';
  
      // DEBUG: notify on network state
      console.log("Connection type: " + states[networkState]);
  }
  </code></pre>
  
  <p>Is there anything else I need to do (add an event listener?) to get this to work?
  Normally a device will only fire an event when the status changes from online to offline, but I need to distinguish between 'free' internet and xG connections.</p>
