Signal Protocol goes way beyond PGPs default security offering with Forward Secrecy 
and much more.

One of those cases where the crypto is way stronger than the environment in which it 
exists. Tramps living on park benches exchanging messages by armoured cars is the 
favoured analogy I believe.

Although maybe I'd call IPhone's a cheap rented flat, the landlord (Apple) could 
still pop in, and the walls are made of plasterboard (aka Unix).

Pragmatically, if you want this sort of level of protection and decent network 
effect use WhatsApp, and tweak the settings.
