RIM has started rolling out OS 10.0.6.545 to BlackBerry 10 Dev Alpha devices. As of now there is no change log for the update so we are not sure what this update brings as far as fixes or enhancements go. So if you have a BlackBerry 10 Dev Alpha device get out that USB cord and give your device a fresh new update. In order to perform this update you will need the latest version of desktop on your PC. As always let us know your findings/fixes.
