OS 10.2.1 will be the next big update for BlackBerry's operating system. A new leak has hit the web, and can now be loaded on certain devices only, for the time being. Those with Q10s, Q5s, or Z10 of the STL100-1 variant can load this bad boy up right away. Unfortunately, those of us with Z30s or Z10s in the Americas, and Europe will have to wait.
As always, if you don't know what you're doing with leaked OS, we recommend avoiding them. We don't take any responsibility if you jack up your device during this process.
