Whatever AK1 and KS1 mean, I guess it means we will at a minimum get features like file system encryption in SailfishOS, and who knows what more. For Turing they already developed a fingerprint reader. I like that, as absence of security is a barrier to adoption by businesses and governments.
I hope that after RussianPost, more agencies will follow. An order for 771,000 phones for the Russian Armed Forces would keep Jolla going for some more time :-)
