YUP, the newer phones do not interfere with planes et.al...
it was the older-gen ones (analogue?, I don''t know the terminology) that would interfere with the planes... these have been out of circulation for something up to 10 years (in Australia at least)...
from watching LAW & ORDER (lol, i know my source is really reliable):
if you used the internet to make the "call" and spoke over the computer's input and output devices... that would make the call only traceable to your local server... and many programs exist now that would do the A-B-C-D thingy mentioned above, in a random pattern, making the "call" virtually untraceable... in a much more readily accessible fashion...
also
some numbers themselves are "Silent", meaning that ordinary phones will not trace their source for caller-id etc. and even top of the range tracers find them hard to trace...as the phone-company does not release the number.... a lot depends on the equipment tracing the call, and the length of time spent connected, as it allows for the tracer to have longer access to your details...
