I think there's a couple of possibly critical factors here, not yet discussed.
1) The proximity of the TRANSMITTING mobile, to critical aircraft control and navigation wiring lumes running alongside the cabin... ? (more detail from any engineers out there?)
2) A mobile remains dormant (so to speak), when out of range, such as in high altitude cruise etc but has maximum output/interference when sending and recieving calls, once in range. This appears to be when the most trouble documented has been encountered.
Safety first!
