The latest version of the Bluetooth specification is official, though compatible products aren't expected to reach consumers for another 9 to 12 months. The new spec adds the ability to switch over to an 802.11 radio for fast data transfer speeds. It is completely backwards compatible with older Bluetooth devices, and still uses the same protocols for establishing connections. But if two devices support the 3.0+HS spec and have an 802.11 capable radio, then it will be utilized for large data transfers.
