> I think I know what a radio phone might do. Radio clocks even exist I assume a radio phone would be a walkie talkie, and those can still be useful. Further, I used to have a cheap mobile phone that had a built-in FM radio, but now I have a much more expensive smartphone that doesn't -- or at least, it's not user-accessible. I also have a somewhat old radio alarm clock that gets the correct time via the mains power supply. Needless to say, the time goes wrong and you have to turn it off for a while then hope it gets the right time when it restarts. Usually it does, but sometimes it can be hours wrong for weeks. I could use my internet radio as a backup, of course, but the broadcast sound arrives way ahead of the internet sound, and if the two radios show the same time as the smartphone, that's looks like luck. Seems to me we've been screwing these things up for a while, even without the internet of things ;-)
