Earlier today we saw BlackBerry 10.3 screenshots surface. The upcoming 10.3 release looks to give BlackBerry 10’s UI a more flat look, coupled with some refinements and new features. BlackBerry 10.3 is expected to release much later in the year.

Though, if you’re looking to get your BlackBerry 10.3 fix earlier rather than later, you’ll be happy to know the very early build has leaked for the Z10 (STL100-3). Once some OS hybrid developers break open the OS and repackage it for other device models we’ll update this post. Until then:

*DISCLAIMER* – This is an unofficial software release. There are no guarantees that it is stable. You may damage your phone. We assume absolutely NO responsibility for any damages that may occur. Install this leaked software release at your own risk.
