Hi Mark,
Here is more info. Look at page 22 of the iPad manual:
Bluetooth
You can use iPad with a Bluetooth keyboard for wireless typing, or Bluetooth headphones for wireless listening.
Pairing Bluetooth Devices
You must first pair the keyboard or headphones with iPad before you can use them.
Pair a Bluetooth device with iPad:
Follow the instructions that came with the keyboard or headphones to make it discoverable.
In Settings, choose General > Bluetooth, and turn Bluetooth on.
Select the keyboard or headphones and if prompted, enter the passkey or PIN number. See the instructions about the passkey or PIN that came with your keyboard or headphones.
AC said it has to be 2007 keyboard or later. That is NOT what the manual says. Further, I told AC that the keyboard pairs fine with my Mini which was purchased earlier this year.
Keep in mind that your credit card company is on your side. I have a Genius Bar appointment Tuesday, April 6. I will ask them to give me a wireless keyboard. If they will not, my next call will be to American Express.
