MACityNet reports that Mitsumi is delivering in good quantities its Bluetooth USB Adaptor WIF-0402C as an alternative to the unavailable D-Link DWB-120M Bluetooth USB Adapter from Apple, with the same form factor. Also check out their Complete Guide to Cellular Phone Connection for the Mac matrix. [Update: Koen Wastyn was able to order from this German site: http://www.ccs-shop.de – click “Suche” and search for Mitsumi USB. He also confirms that it works with Mac OS X.]
