Gizmodo has the details on perhaps what is one of the most promising showcases of upcoming technology from the 2009 MWC. Officially specified as "alternate MAC/PHY", you will now be able to have peer-to-peer connectivity coupled with Wi-Fi transfter speeds seamlessly and easily. Devices will shake hands via Bluetooth when paired up. Then, when any file transfer begins, communication will take place over the Wi-Fi hardware giving you a speedy wireless transfer. After the transfer is over, the Wi-Fi connection is dropped and communication is resumed via Bluetooth.

The Bluetooth Special Interest Group says that the specification will be official in April. Fortunately we might not have to wait long to be able to use it. Broadcom states that some of their current production chips already have the ability and only a software upgrade will be required to implement it.
