I had to respond to this, in the middle of the usual anti-FAA rant from
someone who obviously feels wronged by them:

bunch of HOGWASH

Whether or not they do, there's another part of this that the FAA has no
control over: the cellphone network's fundamental design, reaching down to
the lowest levels of the system's architecture, assumes that a single user
phone will be seen by a small number of cell sites. A cellphone in the air
can be seen by lots of cell sites. This confuses the system. The FCC has its
own ban on cellphone use while airborne, and has been known to fine people
for it in the past.
