Bluetooth Phone Management Software
Anyway if you guys check out http://fma.sourceforge.net/ - FloAt Mobile Agent is an AMAZING software that synchronizes your phone contacts with Outlook and the phone over bluetooth.
It also allows you to send and receive messages from the PC, as well as make and receive calls.
They are currently working like crazy to keep adding to it.
They as yet do not support calendar updates. But it might come soon.
I started using it a couple of weeks back and it ROCKS!
And no I am not part of their development team or stand to gain financially.
