When I had my kidney stone attack over a year ago and had to go to the emergency room, I asked the security guard if I could use my cell phone in its airplane mode i.e. all radios off (I had some reading material on the memory card).
Not only did the guard understand what I was asking, he even pointed out that the major problem with cell phones in hospitals was not with the cell phone radio, but with the Bluetooth radio! When hospital equipment started to go crazy, apparently it always happened when the phone had its Bluetooth radio active. If the phone didn't have Bluetooth or the Bluetooth radio was off, there was no problem.
Still, it isn't very reassuring. I've yet to see any consumer electronic product anywhere be adversely affected by any of today's modern cell phones. But put a cell phone near some hospital equipment and it goes crazy? Just what kind of knuckleheaded medical equipment engineers are designing this stuff that they can't even figure out how to build a proper Faraday cage?
