This one slipped under my radar but Phil thankfully pointed it out. In their detailing of the latest BlackBerry 10 native SDK they mentioned the additional support of new Bluetooth profiles and APIs. One of the profiles they mentioned is Bluetooth Low Energy (LE) along with Serial Port Profile (SPP) and Generic Attribute Profile (GATT). Bluetooth Low Energy is a really cool profile that allows for low power Bluetooth devices but requires Bluetooth 4.0. I guess that means RIM is confirming Bluetooth 4.0 in BlackBerry 10!
