The FCC prohibits using cellular phones on aircraft, but that applies only
to cellular phones, few of which exist any more. Most modern 'cellular'
phones are in fact PCS phones, which are not subject to that regulation.

Actually, they are subject to the regulation when they operate inside
the AMPS band regardless of the technology used. Many of the PCS
services fall back to AMPS. Some of the other wireless providers do
digital service in the AMPS band as well.
