If you have a BlackBerry Z10 STL100-1, you will be able to test the first leaked version of the new operating system for your smart phone.
The BlackBerry OS 10.1.0.1609 has been leaked and is making the rounds. This is not an official release and therefore comes with no BlackBerry support behind it. If you decide to update your BlackBerry smart phone with this new version of the operating system, you are on your own. But you will be able to find help on many online forums.
If you decide to go ahead, you will need a computer running the Windows operating system to be able to run the autoloader for your smart phone. Also, you will have to download the leaked operating system, from here. Before you proceed with the installation, it is recommended that you backup all your data.
