You got one to work? I'm still having trouble with mine after getting the 3.2 update. It pairs, but still won't connect. When I try to connect it, I can see a message flash up indicating to press a PIN #. But it flashes so fast that I can't quite make out what it says.
Try typing a pin any way if possible and see what happens. Usually pin is either 0000 or 1234. If you are paired that usually means you are already past the pin input. To connect you need to open an app with a text field and long press where you type. Then select the input method which in this case should be th BT keyboard.
Mine likes to sit on paired but not connected also, I found it quickest when that happens to just delete BT profile of KB and just re - pair. Links up just fine after that. That is until the next time it drops out.
