Mythbusters actually did a show about this one. they proved that it actually does interfere with the guages they use for landing, but it wasnt enough to cause anybody with any kind of flight experience to miss their landing target. which is probably why the airlines ask you nicely to turn off your phones instead of demanding it.
who gets service at 35,000 ft anyways?
