Not officially supported because it really isn't. It works though. You just need to initiate the first pairing from the phone. Then after you enter the code your computer a box pops up that lets you select iSyncing. If you use the BT setup assistant from your computer the phone will pair, but you can't select iSync. Also the icon in iSync shows up as a k700.
It took me a bit to get it working the first time, but after it's setup all you do is run iSync and it works without a hitch.
