title: Android C2DM getting NotRegistered response
body: <p>Thank you for reading my post:</p>
  
  <p>I had C2DM working perfectly in my application.  To test a different scenario I unregistered my phone so that it would not receive pushes anymore, and then I re-registered my phone.  Since I have re-registered push does not work.  </p>
  
  <p>Here are the steps I'm experiencing:</p>
  
  <ol>
  <li>My phone receives a registration_id with no erros</li>
  <li>I do a post to Google with my registration_id within a few minutes of receiving the id</li>
  <li>I get a response of Error=NotRegistered</li>
  </ol>
  
  <p>I don't see anything strange in LogCat during this process.  I'm at a loss and any help is much appreciated.</p>
  
  <p>Thank you,
  Matt</p>
