I really wonder what the truth is on this matter; I will conjecture due to carelessness, forgetfulness or just being ornery on any given flight there are several cell phones, computers, Ipods, electronic games etc. left on by accident or on purpose. The aircraft can't possibly be that vulnerable to the emissions from these devices otherwise we wouldn't be allowed to board with them. I suspect something happened to the nav system or autopilot on an obsolescent aircraft when someone played a Walkman in first class; there was an overreaction and now we have the electronic equivalent of "no swimming for an hour after you've eaten otherwise you'll get cramps and drown."
