title: push data from webservice to android app: C2DM
body: <p>I have a use case where I need to send some information from my webservice to an Android App. I just got to know about C2DM which is used for such use cases (correct me if I am wrong).</p>
  
  <p>Does someone know how much latency one can expect while using this service? In my use case, I want the message to be sent from the webservice to the phone within 1-2 sec. </p>
  
  <p>Has someone used C2DM and have an idea of how much is the average message delay? Thanks!</p>
