Here's some sad news that came late yesterday in a Tweet from Motorola. Apparently, older devices are not going to get access to Moto's new Unlock Tool. This includes devices like the Bionic, the Droid 3, the DX2 and more. They didn't specify what constitutes an "older" device, so we don't have anything more specific than the above mentioned devices. Right now the only thing we do know for sure is that the Xoom, Photon Q 4G LTE, and the European RAZR Developer Edition are the only devices supported. We will do some digging and see if we can find out more.
