The best part is that while perusing /. I found a pertinent article relating to this problem. A possible solution: nano-paint that can block cellphone reception (essentially radio signals) on command. They do that by inserting copper nanoparticles into carbon nanotubes. FInally our movie theatres, schools, and other indoor public places will be free of annoyances. Although, I can forsee some problems such as people who need to interrupted for emergencies such as doctors. But that would work well in airplanes. That way the flight attendants don't have to pester travellers to shut their phones off. They can flip a switch and cut off their reception.
Honestly, the planes need better electromagnetic shielding. Work on that. You spend billions of dollars in R&D and you can't fix this issue?
