The cellphone interfering with navigation BS has always been a smokescreen IMO. I've left my cell on accidentally on several occasions....I can even hear it ringing in my carry-on occasionally. And I know of several people who use the lav to make phone calls while in flight.
Next time Mr. Big is in the lav for what seems an unnatural amount of time, consider that he's probably closing a deal rather than answering nature's call.....
