I'm not convinced of this, though if you have a citation for it I'd like
to see it.  Would be easy for someone to verify with a frequency counter,
I suppose.

I'm pretty sure my phone doesn't transmit a signal when it's off because I
can hear the data bursts interfering with my car radio when it does
transmit.
