Ah. i found. it looks like pretty cool phone. $799 more expensive then 450 CAD i paid for the dtek50.
They claim to be the first but I doubt that. I bb has been doing this for at least a decade.
Dtek comes with specilzed chip that protect the phone from the moment you start it the first time.
Blackphone 2 doesn't mention any special chips, or i could not find mention in the specs at least, and that is where the dtek50 is stronger i'd say.
But i am no expert and the Dtek50 ffers enough security for what i need for the price i paid.
The Blackphone 2 does look sexy.
