CNET writes the Bluetooth 2.2 standard is expected to be released in mid-2009. The new specification will allow much faster transfer speeds:
According to the SIG, the new High Speed Bluetooth specification will work in conjunction with WLAN or USB for improved data rates, and will be known as Bluetooth 10x and Bluetooth 100x, respectively. It will hopefully allow for wireless video streaming, wireless printing, and more. For this to work, your cell phone will have to have WLAN or UWB radio. It's said that Bluetooth 10x will be used first, since a lot of handsets have Wi-Fi capabilities now.
