1) Does anyone know if there are any PRISM-free mobiles still in production?
By PRISM-free I don't mean encrypted / anonymous talk (like Cryptophone) but rather something impossible to control remotely (no remote pictures, no remote wiretapping, no remote start/shutdown)
2) Are there any good PGP / crypto SMS apps that work both on Android and Windows Phone?
You could take a rock from your driveway, and tape a piece of paper that looks like a cell phone to it.
EDIT:
Be sure to cover it with tin foil!
