Someone recently asked me (because they seem to think I know about
phones and stuff) what the little exclamation mark in a triangle was on
her phone display.

"Oh, I said, that means that for some reason your conversation is not
encrypted across the radio link to the base station. Probably a glitch
in the phone network, I've seen it once or twice before"

Her reply was to the effect that she couldn't see it mattered really
"as anyone listening in would do so at the exchange wouldn't they".

So maybe most people would not be concerned if their phone sent en
clair.
