As I mentioned in another thread, the theory by which cellular networks have trouble or even can be crashed by airborne handsets, is totally false. Such networks and its components are built to be rugged and resilient. If anything like that

Not even at level of audio signal. GSM merely interferes with the speaker coil itself. That is why you can hear the noise even if interferenced device is off.
