By now, I'm sure a lot of you have installed the latest 10.2.1 leaked OS. We first saw it drop for the BlackBerry Q10 and BlackBerry Q5 and, surprisingly the BlackBerry Z10 STL100-1 model, which usually gets left out. Soon afterwards, if finally dropped for BlackBerry Z30 and Z10 owners who were itching to try it out.

So good and impressive were the new features on this latest leak that it made me break my no leak policy on my main device. The forums are buzzing with people discovering all the neat little additions to be found, like contact profiles, new BBM icons and the ability to install APK files directly.

In CrackBerry fashion, we're bringing a video walkthrough of some of the cool new features available in OS 10.2.1. From the awesome pinch gesture in the Hub, to custom quick settings, to Device Monitor, even the new call screen. Don't forget there's also the new Pic Password too. There are probably lots more new things to discover, as well as more to come when the official version drops. Until then, check out the video above and then hit up the comments and let us know what you think.
