>>I've never seen a cell phone (specifically an iPhone 5, A Nexus, a Samsung Galaxy S4, and a razr flip phone) transmit with airplane mode turned off.

I think you meant "on"? If airplane mode was on, RF emissions were a strict test case executed in the lab Faraday cages where we ran new terminals through their paces prior to launch rollouts.

Correct, typo. We were specifically testing the radiated and conducted (through its charging cable) emissions from the cellphone's processors, display, etc, and needed the radios off in a reverberation chamber.
