The nices story I heard, I know the people involved so it's not apocrophyl (?) is one of my previous airlines A321 coming in to Heathrow with a CAA Flight Ops Inspector on the jumpseat. As the aircraft comes below 6000', Captains mobile aquires a cell and LOUDLY receives a text message.
I am sure many have heard airport transmissions being made where the log-on chirp of a mobile phone can be clearly heard over the broadcast.
There were several alleged incidents of navigation/autopilot degredation, but so far I have not heard of any accident or fatality directly to the presence on an active mobile phone. I stand ready to be corrected.
