BlackBerry 7100t no like SE Akono

If anyone out there figures out how to pair a BlackBerry 7100t with a Sony Ericsson Akono Bluetooth headset, please [let me know how]( pairing) you did it. So far, my attempts to get this to work for my wife have failed. The CrackBerry refuses to see the Akono set. It sees every other Bluetooth-enabled device in the house, but won’t see the headset sitting right next to it.
