That was the point. It only takes once, and except for 
catastrophic mechanical failure that is extremely rare, 
most aircraft "accidents" are the result of a failure 
chain including a significant error by the fight crew.
Anything having to do with navigation and terrain
clearance falls into this category.

In the case of a cell phone, it would take spurs from 
your cell such as might develop during negotiation and/or 
ring, plus an entry point such as poor aircraft antenna 
cable shielding AND inattention by the flight deck crew 
so that they relied on an indication they should have 
known was false, had they been paying attention. Secondly, 
this only applies when you are arriving or departing "in 
the soup."

If it's what pilots call "severe clear" or even partly 
cloudy, I wouldn't be concerned if all the cells in the 
plane were on.
