Except that an email is a short burst of data using a fair amount of bandwidth for that time. Voice communication is low bandwidth over a long period of time. That could play a factor in how a cellphone might affect electronic equipment. For instance, a compass that quivers for a second or two, versus a compass that settles a couple of points off north for the entire time span of a long conversation.
