Remote controlling Keynote for iOS via Bluetooth

As mentioned above (and maybe I should put it in bold above the article): Apple broke the Bluetooth connection in iOS 5. It should still work via WiFi.

Let's hope they fix it again in a later iOS release. Sending them some feedback can't hurt either ...
