Hospital cellphone ban under the stethoscope

We were all "Wutwuut?" when we even found out that those Brits had banned cellphone use in their hospitals for fear of disrupting medical equipment—something at once totally sensible and positively frustrating, kind of like the FAA ban for cellphones in airplanes. But apparently now they're trying to rewrite the blanket law and make it a little friendlier for people to make calls outside areas of risk (i.e., the E.R.). Would that be, like, say, in the parking lot? They also want sort out dealing with lower-interference wireless devices so the staff can still be connected while on site; for all their sakes, we're going to try and make sure they don't find out about extreme Bluetoothing.
