one of the new features of the iPhone 3.0 -- is ability to use Bluetooth, but i can't find any documentation about it. can someone point me please -- where is it?

Answer 1

The only way of using bluetooth directly is if you join the Made for iPod / Works With iPhone program and integrate the Apple authentication chip into your custom device. Once you've done that, you can use the ExternalAccessory framework which exposes a low-level IO stream API to the device.

Frameworks like Core Audio will let you play and record music via bluetooth headsets and the Gamekit framework will let you discover and talk to other devices via bluetooth, but the fact that it's bluetooth is not exposed to the developer at all.
