Yesterday we saw OS hit the streets for most BlackBerry 10 devices, and today we can add one more to the mix — the BlackBerry Z3. Even though the Z3 has yet to be made available officially, we're sure that some of you are sneaking around with them and keeping your lips sealed. To help enjoy those pre-release devices — or for those looking to break down the Z3 OS — it's here for the taking.

As always, be sure to perform a full backup using BlackBerry Link before you install any OS. Check out our full tutorial on using an autoloader here and don't hold us responsible should anything go bad — though you can always reload your OS.
