After a few early hints last night, BlackBerry 10.2.1 has started rolling out officially on the AT&T Z10 and Q10.
BlackBerry 10.2.1 adds in quite a few welcome features, such as a pinch gesture in the hub to filter the view, direct installation of Android .APK files, a customizable quick settings menu, and many, many more new features. If you're looking to update, just swipe down from the top of the screen, go to Settings, and scroll down to Software Updates.
AT&T customers, do you already have 10.2.1 on your BlackBerry Z10 or Q10? Was it worth the wait?
