The BlackBerry OS 10.3.1 developer SDK has just been released and BlackBerry released the full OS with this build! Do note that this is just an SDK and a developer build, and not a consumer or public build! So test this, at your own risk!
Sorry, at this point, it seems like P’9983 and Passport is not here yet!
