+1 better follow the rules than sorry....

"... The primary concern is that cell phones may interfere with the navigation and communication systems of the plane, potentially resulting in devastating failure. Numerous airlines have reported disruptions in cabin pressure, compass function, and wireless navigation systems associated with the use of cell phones on board."
quoting from same site...

As a pilot I will go ahead and say that most phones do not make a lick of difference in the plane. However, a few do. I was taking my father on a cross country flight the other day and my dad was doing business on his phone (so busy, ha ha) and I couldn't figure out why I could barely hear approach and they could barely hear me.
So after about 15 minutes, I asked my dad to turn his new Iphone off and voila! I was able to communicate again with approach. Coincidence? Maybe. but if it was the phone and I was in IMC that could have been fatal.
Sure, a phone in the back of a 747 might not make a difference but the FAA puts the rule in place for everyone, not just certain planes. It's universal - anon128195

I am a flight attendant and would like to add my two cents' worth.
Yes, it is an FAA rule to shut off, not just put to sleep, your cell phone during taxi, take-off and landing. But the other reason is that taxi, take-off and landing are the most dangerous part of your journey on a plane. And if an emergency is happening, we as flight attendants, need 100 percent of passengers' attention.
If a large portion of passengers are on the phone and we have to run around the cabin getting everyone's attention to follow instructions, it could cost valuable minutes and possibly lives.
Just a side note: stop acting like seven year olds who were told to stop watching TV and having a hissy fit.
There are some things in life that do not make sense and that you will have to do anyway. Stop blaming the flight attendants for the FAA rule. Call or write to the FAA. - anon134477
