title: Remove App badge with a silent push notification?
body: <p>I can see in the documentation that there are ways to clear the badge by sending a push notification, but is there a way to clear it without an actual alert appearing? I'm thinking of building a chat client, that can check with the server if the message has been received somewhere else. Check is not the right word though, the server should push down to the iPhone if the message got picked up somewhere else, and clear the badge, but it doesn't need an alert or a sound, just a removal of the badge. Can you do this?</p>
