used to work TDMA/CDMA/etc but the newer technologies will NOT work GSM

2) Technically it is a federal violation of FCC regulations to use a
cell phone in flight.

Point 1: CDMA is newer than GSM.

Point 2: The technologies have nothing to do with the ability to get
service while in flight. It has to do with the system design. Most
cellular and cellular like system downtilt the antennas to minimize
propagation form interfering in adjacent areas. The result is that not
much RF goes up into the sky. What does is not set up to work within the
system limitations.

Point 3: The FFC only bans cell phone use for those systems covered
under Part 22. Those systems are ones that use the 800MHz band. So
Nextel and the PCS services that use 1900MHz are covered under different
parts of the FCC and rules and are not precluded from use by the FCC.
