A, uh, custom one.

Yeah, I'm keeping both of those things in mind. There won't be any assumption that your phone calls or SMS will be secure, but rather that your mainboard OS is secure _from_ the radio and that you don't have to worry about discussions had near your phone and such.

The phone network and the protocols for connecting to it are pretty user hostile no matter how open and secure the phone and baseband are though.
Don't forget the SIM card runs its own insecure OS that people have hacked before and you just can't replace that.
