Why should I switch off my tablet and headphones during take-off?

Planes now have WiFi and DirecTV service, and the cockpit is constantly communicating with a tower. How is my phone connecting to a Cellular/3G tower going to cause an issue?

Let's say that the attempt to connect to a Cellular tower does bad things. What's the problem with the following devices being switched on during take-off and landing:
- noise-canceling headphones
- DVD player playing a movie
- iPod playing music

Do these devices create a harmful electromagnetic field only during take-off and landing? Airlines and rules need to update themselves to be relevant in the 21st century.

Update: Airline pilots can use iPads in the cockpit for the duration of the flight. Read this followup for some EMT findings:
