The ban is not an FAA ban, and has nothing to do with the flight control systems. The rule is an FCC rule, and the concern in saturating sell site slots as a single phone could tie up slots on many more cells from 35000 ft with no abstructions. I have read the Boeing reports on interference that is the basis of "no electronic equipment below 10000 ft." It documents a small (10s) set of problems (often with the autopilots) that were not reproducible by Boeing even when they had the unit in question and did every test imaginable. But the FAA says that the Pilot in Command can do anything they want, and rather than having the pilot have any choice the airlines put in blanket rules about 10000 ft and below, which has been interpreted to be a critical area of a flight. The FAA regs say that all attempts to allow us of equipment whenever it does not have problems, but that is always subsumed by the pilot in command rules. jerry
