Even if you can prove that they do not interfere with any aircraft system nor ground network including those not standard GSM such as the US and Caribbean etc. and those are two pretty big IF's there is yet a third hurdle which according to "INFORMATION AGE" is that:-
Quote-a recent IDC study of 50,000 American passengers found only 11% were in favour of phone use irrespective of the area of the plane.-endquote
The last thing passengers want is to be doing a long night flight in economy next to some selfish individual calling all his friends telling them that "I can't talk for long because I'm on the plane".
At the moment airlines prohibit their use, and that is known to the passenger when he books.
To take it out on the cabin crew by arguing at length that "my phone is ok because of this that or the other", is not on, but such behaviour is an everyday occurrence.
