Today, Apple updated the MacBook Air with the Bluetooth EFI update 1.0. Apple has yet to tell in any support notes what this update actually does.
However, for those souls that are willing to download and install the latest (un-noted) updates, you can find this update in your MacBook Air's Software Update app (Apple Menu > Software Update). You can also download the 1.2MB update from the Apple support downloads website.
Thanks to everyone who sent this in!
[Update:] Since posting this story, Apple has updated the link information and has taken off the "EFI" on the title of this update. You can find the update information here.
