Although there has been plenty of leaks for several of the the BlackBerry Z10 variations, non of them have really targeted the STL100-1 versions out there. That appears to of have changed now though as a new release is making its rounds. OS has now appeared online and is ready for testing. At this point, we don't have an STL100-1 to test it on, so you really are flying on your own with this should you decide to give it a go.

You'll again need a Windows PC to run the autoloader for your device, and of course this isn't an official OS and thus has no BlackBerry support behind it - so use caution when installing and don't complain if it breaks anything. We do recommend performing a full backup of your device before you fire it up ... just in case.  If you don't know your Z10 model number you can find it by going to Settings > About. Plus, you can always hit up the forums for help.
