Am I right in assuming one would not be allowed to USB tether a phone to a laptop to receive internet while on a flight? This would essentially be the same as talking on the phone during flight and is prohibited right? Just wondering as I just got tethering working and it would be nice to have internet during flights, a google search yielded NO relevant results so either I am stupid or no one has thought to try this yet? I am skeptical as to how much 'interference' a cell phone signal really causes to airplane instruments. Would they really be dumb enough to have anything operating on the same frequencies as cell phones? My dad is a aircraft mechanic for USairways, I will ask him today and find out. Any thoughts folks?
