Users who are privy to installing leaked OS builds will be happy to know that there is a new one on the streets. BlackBerry 10.2.0.810 has leaked (or at least been manufactured) for the Z10 versions STL100-2/3/4, but not for the 100-1.
Early reports suggest calls work, there is Jellybean (Android 4.2.2 runtime), but a good portion of apps may not work due to 10.2 incompatibility.
*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.
