Im the owner of few old blackberry devices
the older one is a curve, running qnx 7
the newers one runns blackberry 10. It have a v4 android compatibility. I succced to install old fdroid on it, but impossible to refresh repositories (ssl certs error?)
I’d like to know how to install fdroid and make it working on those? in a way to install xmpp and sip clients, as possible?
