For lack of a better word does the 8130 have an "Airplane Mode"? Basicly a way to turn off any two way signals that would then allow you to use it other features like it's MP3 player while on a commercial aircraft in flight?

well not necessarily. any steward/ess in america might not actually care but your phone is capable. go to the manage connections icon and turn everything off there. This will turn your radio to OFF. they may still tell you to turn it off (and after saying once that you turned all transmissions off), if they persist, just turn it off.

yes even though airplane mode might meet FAA regulations for use during a flight, the actual airliner can impose their own regulations as well. so it varies.
