With BlackBerry 10.3.2 being tested through the BlackBerry Beta Zone, BlackBerry has now taken the next step and made the 10.3.2 beta autoloaders available for developers as well. Interestingly enough though they are a version behind what is being offered in the Beta Zone. Software version 10.3.2.159 is what’s available through the autoloaders while Beta Zone is offering software version 10.3.2.304. In any case, BlackBerry has outlined what developers need to know about these autoloaders.
