My cousin is a BBC cameraman. He doesn't use a smartphone. I've just spoken to him (in Austria doing a report on something) and he just laughed at the suggestion this is common practice. PS: Just had a text, reporters are trained to use a smartphone but only when they have no other means of recording, eg: when they are first on the scene at an incident. But they are told not to do any interviews until the cameraman and soundrecordist get there.
