A few facts to mix in with the emotions.
1) GSM mobile phones DO interfere with aircraft avionics. All VHF radio in aircraft are AM and GSM phones cause a bzzzz/click/click when they are being used.
This is not a huge problem in cruise but on approach/departure or in the circuit this can get you killed. Remember you are told to turn off all gizmos at top of descent?
GSM phones also upset the ADF and can make a VOR wobble. I have not had experience on a glideslope (ILS) as I am NOT THAT BRAVE (or crazy).
2) CDMA/Analdog phones work great at 10,000ft (and a bit) GSM goes nuts. This is not second hand info. I have not tried NextG yet, will soon.
3) Newer heavy jets have much more clever stuff but if the EFIS fails then they all go back the standard asi/alt/ah/vsi/tc/dg and as they are always IFR will be back on traditional navaids. I would not like to be in that situation and have something interfere with ANYTHING, particularly in IMC.
Now I am sure there is lots of pressure to have mobiles working everywhere and there are lots of places where they are used in flight, usually asia, usa, europe & africa, but then this is where most of the splats happen too.
Whether there is a connection or not I do not know for sure.
What I do know is that blind people cross the road safely all the time but when I cross the road I keep my eyes open, just in case......
