It didn't take all that long but it sure felt like it - OS 10.2.1.1055 has now leaked in full for the BlackBerry Z10 and Z30. We've already seen the same OS for the Q10/Q5 but the Z versions sadly had no radios or autoloaders. That all changes as now everyone can get in on the fun.
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).
