Sick of Apple's 'Temporarily unavailable' Bluetooth dongles yet? The BT-DG02 Bluetooth dongle from Epox is available now, $49.95 MSRP.
I ordered mine directly from Epox (free ground shipping, see Accessory ordering on their web site) and received it within a week. Works great with Apple's Bluetooth Preview 2 and my Ericsson T68. It is a little bigger than the 'temporarily unavailable' solution.
