If you've yet to get the BlackBerry 10.3.3 update or are simply just looking to a newer version than the one you have, you can now download the OS 10.3.3.2205 autoloader files needed to manually install it.
At this point, it's hard to say what all is new in the updated files as, well, they're simply too new and folks haven't had time to explore them but, the one thing we do know right now is that they're not that much older than the previous build. The previous build was created on December 8, 2016 and this build was created on December 12, 2016.
All that is to say, chances are there's not a lot of changes within this release but rather some smaller bug fixes. As always, the files made available in the forum are provided as-is but if you simply cannot wait for the official OTA to be sent out or are on a carrier in which updates are not provided, using the autoloader files are the best way to get your device updated.
