Along with the Gold BlackBerry 10.2 SDK downloads, BlackBerry has also updated the BlackBerry Dev Alpha OS autoloaders. When updated, Dev Alpha devices will be running OS 10.2.0.1157. The links have actually been live for the past few days but now, they're fully official. Keep in mind, these downloads are NOT full builds and are specifically meant for developers. In other words, you're not going to want to use these as 'daily drivers' on your device.
