This was not about cellphones but GPS receivers. I doubt your arguments will void IATA regulations. Regulations are not based on rubbish but on facts. A radio receiver typically includes an antenna, a tuning circuit and and LNA amplifier. If the receiver malfunctions it can become a transmitter and jam other systems. This is very unlikely but if the regulation was not there there might have been casualties among millions of flights due to this risk. Hope you understand my repetition better.
Wires have been insulated even on ancient planes. A GPS receiver might malfunction and start transmitting broadband noise that diffracts out from the plane windows and reflect from the wings to be picked up by the planes antennas and screw up navigation. This kind of malfunction is very unlikely, but still possible. You really think they make the laws just for fun. I would not risk the lives of people.
@BadaBing628 Well, that's just the point. A GPS receiver has a tuned antenna and/or additional filters tuned to the GPS frequencies. A feedback condition in the LNA could cause relatively strong oscillations in the frontend and cause radiation at the frequencies used by the aircraft's navigation receivers, blocking the satellite signals. GPS receivers can also be very sensitive to impulse noise. Check NTIA Report TR-01-384. Also the GPS has more energy in the battery than a watch.

Using any GPS receiver on a plane is forbidden during flight. This goes for all radio receivers. Any LO leakage from a receiver can in theory mess up the navigation of a plane. It only a matter of time when planes start to crash because of increasing interfering gadgets in the cabin.
Using a gps reciever is perfectly safe on any aircraft, the units do not transmit anything at all, they on recieve info. If using a GPS on a cellphone, then make sure that it is flight safe mode.
wow, lucky for you....I tried to get my GPS to connect on the plane, and the only way it would work was intermittently when I held it at an angle right next to the window, but, for the short time I could get it to connect, It said I was going at 800.2 KM/H
cool .. I enjoyed it.

A simple GPS reciever couldn't malfunction and transmit broadband noise any more than an ordinary electronic watch.

What plane were you on? I was on a 737- 800

Hi, yeh you've got to hold it next to the window but it works quite well.
Oh, and it was a 737-300

This is the 'sports tracker', available free on the nokia website.
...and yes, the N95 can be used on flights in 'offline' or 'flight' mode.
