The iPhone has Bluetooth 2.0 EDR built-in, but so far it seems to carry little functionality outside use of accessories like the Apple Bluetooth headset.
Apple's Bluetooth File Exchange for Mac OS X cannot send files to the iPhone stating "Device does not have the necessary services."
iSync for Mac OS X cannot be used to synchronize with the iPhone via Bluetooth, delivering the message "iSync can not connect to this device."
We've yet to hear reports of Windows applications that can successfully interact with the iPhone via Bluetooth.
So, what can be done with regard to computer-to-iPhone Bluetooth interaction? If you know, please drop us a line.
