Along with the new SDK BlackBerry has updated the Developer SDK OS to BlackBerry 10.2. This new version is available for the BlackBerry Z10 and Q10 along with the BlackBerry Dev Alpha B and C. Once again these are trimmed down versions of the full OS so expect many things to be missing like the alarm clock. In other words this is not for day to day use! BlackBerry has also updated the simulators to 10.2 which have everything but the new Android 4.2.2 runtime.
