title: Navigate to a new page without putting current page on back stack?
body: <p>In an Windows Phone 7 application I got a CurrentPage, which, on a special event does navigate to a new page using the NavigationService:</p>
  
  <pre><code>NavigationService.Navigate(new Uri("/NewPage.xaml", UriKind.Relative));
  </code></pre>
  
  <p>Now when the user clicks back on the NewPage I want the app to skip the CurrentPage and go directly to the MainPage of the app.</p>
  
  <p>I tried to use NavigationService.RemoveBackEntry, but this removes the MainPage instead of the CurrentPage.</p>
  
  <p>How do I navigate to a new page without putting the current on the back stack?</p>
