The  hospitals are afraid of allowing anything that was once banned -
what if  something bad did happen? Oh my!


well, from an Radio Frequency Interference standpoint, there was a point to  
the ban, 10 years ago, when bag phones could exceed 1 watt effective radiated  
power, and many telemetry systems operated on frequencies in close proximity 
to  the analog cell phone frequencies...
 
More of a problem was present when most telemetry systems operated on the  
150-160 MHz bands shared with public service hand held radio services...those  
old Motorola 'bricks' could produce up to 3 watts of power, and a medic's or  
peace officer's radio could hash a whole telemetry wing.
 
with the much reduced power of the new digital phones, and the separation  of 
most of the cell phone bands from the telemetry link bands, this is no longer 
 a problem.
 
Same with the bans on pacemaker patients from microwave ovens...while still  
theoretically a risk, when was the last time you actually saw a patient who 
had  a problem from microwave *oven* exposure?
