While AT&T has rolled out OS 10.0.10.822 (software version 10.0.10.116) officially, if you happen to have a Euro BlackBerry Z10 (STL100-2) you too can now have the update, provided you don't mind loading a leaked OS onto your device. Unfortunately, it will require a Windows PC to install but if you're willing to give it a go, you can hit the link below to grab the installer. If it goes downhill, remember you can always wipe and restore your device.
It's been suggested the file will work on other devices, such as the STL100-3 and STL100-4 but for now, if you decide to give that a go, you do so at your own risk. As always - use caution when installing a leaked OS like this and remember if you break your phone it's not our fault. Also, a good idea to make a backup because you're essentially performing a factory restore on your device. If you don't want to lose data, a backup is needed.
