title: using UIDevice uniqueIdentifier in iOS5 for Notifications
body: <p>UIDevice uniqueIdentifier is already deprecated in iOS5, can I still use this? I'm using it for Remote Notification by following this <a href="http://www.raywenderlich.com/3525/apple-push-notification-services-tutorial-part-2" rel="nofollow">tutorial</a>, and the current alternative for uniqueIdentifier does not satisfy what I wanted.</p>
