title: Push notification badges not appearing?
body: <p>I'm using Urban Airship to send push notifications to my app</p>
  
  <p>eg:</p>
  
  <pre><code>{"aps": {"badge": 2, "alert": "Part 2 of the August Issue is ready to download!", "sound": "default"}, "device_tokens": ["X"]}
  </code></pre>
  
  <p>The alert will display perfectly, however the app icon is never badged regardless of what I set "badge":# to...</p>
  
  <p>Is my payload incorrect or is there extra code I'm supposed to add to my app to handle badges as well as alerts? Thanks!</p>
  
  <p>EDIT:
  I'm registering for push notifications like this:</p>
  
  <pre><code>// Register for notifications
      [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeNewsstandContentAvailability | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert)];
  </code></pre>
