You have to turn off your phone when the plane door is shut while at the gate, but you can turn on your phone when the plane touches down during landing. I was told this is more to do with the FAA wanting to do everything possible to "encourage" you to pay attention to the safety briefing.

But it means that I doubt much will change given that its not just electronic interference that is the reason for the ban of electronics during taxi'ing at least.
