ok, you have a couple steps to follow to get bluetooth working. I just did it and was able to pair my Apple Bluetooth keyboard to the Pi and have it work.
In a terminal window enter the following
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
NOTE: At one point you will be asked if you want to replace the autostart - You want to keep the original. This will take a long time (i.e.start it and go to the gym and work out) When it is all done, reboot the Pi.
sudo apt-get install pi-bluetooth
sudo apt-get install bluez bluez-firmware
sudo apt-get install blueman
and reboot again. Now when you exit to the desktop, you should see a bluetooth icon at th top right. Use this to pair your devices. It should be noted that there is a chance that not all devices will work, but at least you can try yours now.
