BlackBerry has started pushing out a new beta update to its Android-powered DTEK50 smartphone. Weighing in at 337MB, the update bumps the firmware version to AAH108 and brings along Android security patch for the month of October. Given that it's a beta update, an official change-log for the update isn't available, so it's difficult to say what else - if at all - is included in the update. If your DTEK50 device is enrolled in the beta program, you can check for the update by heading to your handset's Settings menu. Via
