I'm generally not cynical, but I suspect that this feature and the excellent feature to send SMS's through one's phone from Address Book are casualties of a war that Apple has waged on (non-iPhone) smart phones.
Most non-smart mobile phones are happily sync'ed with iSync, but many of the latest smart phones all cannot be. Now, without 'Send this card via Bluetooth', I'm really not sure how I'm meant to use my SE P990i at all with my Mac.
I've already planned to get an iPhone when it comes out, but I still want these features!
Can someone please provide a non-cynical explanation for me? I don't want to believe that Apple would punish us consumers for previously purchasing other companies phones. I mean, the iPhone isn't even out in my market yet!
*Apple, please bring back Bluthooth support to Address Book!* Also, whilst you're at it, please un-cripple the Bluetooth on the iPhone!
