Can't pair 13" MacBook Air with iPhone 4 via Bluetooth I'm not sure why, but I can't get my iPhone 4 to talk to my new MacBook Air 13".  I turn bluetooth on for both devices, open the Bluetooth Preferences and pair the devices.  This works - the code is displayed on the Mac and the phone, I click OK and it looks busy.  After that I get a message on the iPhone saying "[mac name] is not supported".

I have also tried clicking 'Connect to Network' on the Mac and that results in the error "The Bluetooth network is unavailable: There was an error connecting to your device. Make sure the device is turned on and in range".

I'm running 10.7.2 and iOS 5.0.

Well the device (iPhone) is on and in range.  Can anyone help?  I want to be able to control Keynote on my Mac using the Keynote Remote app on my phone.
Have you followed Apples instructions?  

It seems that Keynote works better via WiFi than Bluetooth but the link above shows how to setup both.
