-//    the Connect call fails, this class will delay the notification if
-//    necessary until the Error property is set so that the correct
-//    message can be displayed.
 //    TODO(stevenjb): convert this class to use the new MessageCenter
-//    notification system, generate a notification immediately, and update
-//    it when the Error property is set to guarantee that a notification is
-//    displayed for every failure.

 // 2. It observes NetworkState changes to generate notifications when a
 //    Cellular network is out of credits.
