title: WP7 : How to do some treatment during splash screen, but before the first page is open?
body: <p>In a Windows Phone 7 application, I need to do some treatment before the first page gets opened.<br>
  But I'd like to do it during the splash screen, so the user knows the application is effectively running.</p>
  
  <p>I tried several events :</p>
  
  <ul>
  <li><strong>Application.Launching</strong> event is fired before splash screen</li>
  <li><strong>Frame.Navigated</strong> event is fired after the first page is loaded</li>
  </ul>
  
  <p>Is there any way to do something between those 2 events ?</p>
