Push notification when available but keeping 2.0 compatibility
<p>The new IPhone OS 3 enabled push notifications, which I'd like to use, however, this would be the only feature of 3.0 that I would be interested in. I noticed that the TapTap Revenge application kept their 2.0 compatibility in the store, yet when I upgraded my device to 3.0, I got the popup to enable the notifications. Does anyone know how they managed that? I considered compiling for 2.0 and checking if the UIApplication responds to the registerForRemoteNotificationTypes selector, and calling it if so. </p>
