title: ios unregisterForRemoteNotifications does not work
body: <p>I am trying to get my device unregistered from the remote notification services in my app, so I tried to use <code>[[UIApplication sharedApplication] unregisterForRemoteNotifications]</code>.  But this does not work. My app still shows up on the <code>notifications</code> section of my iPhone's <code>settings</code> app. Is there any other way I can do this? </p>
