Modern GSM phones don't seem to get any coverage at altitude. When I
had my CDMA phone I could send emails when I flow over populated areas.
Now, nothing.

I know the FCC says you're not supposed to use cell phones on an
aircraft (even though recent studies show that such use does not
overload multiple base stations, as the FCC originally feared).
However, has anyone tried it on small aircraft? There is some concern
about cell phones interfering with avionics on commercial airliners
(the jury is still out for most scenarios), but I don't know if the
phones make any difference on a small plane. I suppose it depends on
how much of a glass cockpit you have. Will anyone admit to using
phones on a GA aircraft?
