There were plenty of things we were hoping for with iPhone 3.0, but that list definitely included improved support for the many things we can do with Bluetooth. The list was as long as the feature list for Bluetooth itself and though Apple didn't get everything, they certainly got a lot. Here's the list of what you can (and can't) do with Bluetooth on iPhone 3.0:
- A2DP Stereo Bluetooth. Yes, Virginia, there is a Santa Claus. And come this summer, your bluetooth stereo headphones and speakers will work with the iPhone 3G. Note, it will not work on the original iPhone 2G.
- Peer to Peer. This is a big one, folks, but it's a little strange. You can share files and talk to other apps over Bluetooth. This means you'll be able to do multiplayer games, for example, or 'beam' your contact card from one iPhone to another. Or heck, play a trombone duet. No pairing is required, either. Discovery of other iPhones happens with Apple's Bonjour ZeroConf autodiscovery protocols
- Control Accessories. In addition to the dock accessory control, you can now control Bluetooth accessories from within an app. The example from the event was a glucose meter, but the possibilities are honestly endless.
- Tops on my Bluetooth list: Bluetooth keyboard support. Technically, you will be able to do with with iPhone 3.0. The weird issue there, however, is that this keyboard support would have to happen on an app-by-app basis instead of happening device-wide. That, friends, is a bit of a bummer.
Biggest Bluetooth surprise of the event: confirmation that the 2nd Generation iPod Touch DOES have Bluetooth and they can 'unlock' it to reveal Bluetooth features.
