I know i am supposed to l turn my phone off during a plane ride, but what happens if i leave my phone on ?

I use my phone for my music.

So will anything bad happen ?

Should i just turn the phone off ?What happens if i leave my Blackberry Curve on during a plane ride ?Nothing will happen. Supposedly it would mess with the airplanes signals, but it doesn't. I leave mine on all the time and its fine. Nothing bad will happen, in fact nothing will happen. Just hide it before the initial takeoff.What happens if i leave my Blackberry Curve on during a plane ride ?The airlines ask you to turn off electronic devices during take-off and landing because they can interfere with navigation equipment in the plane. I imgine the chances of anything happening are small, but why not cooperate? It's only for a while.
