There is no documentation on the Apple website that says you can use a BT keyboard. I see a dock, and a dock connected to a keyboard. Even though this has BT 2.1. it's still the iPhone OS running. We all know the iPhone has BT, but you can't attach a BT keyboard. Right? Why would they be selling a Dock, AND a Dock Keybord, if you could already use your BT keyboard?
