Bug description:
  Testing image #u122 this morning, I ran into two separate scenarios
  where the panel network icon didn't always accurately reflect the
  current network technology due to some kind of latency detecting
  network changes ( ie. WiFi -> 3G -> WiFi ).

  Both scenarios were reproduced on mako.

  Scenario 1:

  3G: online
  WiFi: enabled; connected to AP 1

  - display network menu
  - tap another secure network
  - tap cancel when Password dialog is displayed

  At this point the indicator shows '3G' whereas the network menu still
  shows the original AP 1 as connected.  After some period of time ( 10s
  - 1m ), the icon will change back to show that WiFi is connected.

  Scenario 2:

  3G: online
  WiFi: connected to AP 1

  - go to System Settings::WiFi
  - click "Previous Networks"
  - select the currently connected AP/network
  - click Forget Network
  - go back to WiFi settings

  The WiFi settings correctly shows the AP is no longer connected,
  however again the network icon takes some time ( 10s - 1m ) to reflect
  the change back to "3G".
