    Is Blackphone still in business?
    Amazon – sells them – a customer comment claims it is no longer in business. Can’t verify it on Google.

    Hvor er Sailfish henne af i testen? Et styresystem bygget på Debian Linux…

    Har selv kørt Sailfish siden den allerførste Jolla, der ramte markedet i 2013.

    Jeg vil til hver en tid påstå at den er mere sikker endnu nogen af de telefoner på den liste, samtidigt skruer de snart endnu mere op for sikkerheden med den nye Sailfish OS 3
