I knew what I had to do, but now the moment had come: would I buckle? I had been trying out new mobile phones to see how they could be used to support CNN's field newsgathering. Test clips had showed that the phones delivered amazing quality pictures easily.

... As I walked around the armoured car I made sure I'd hit the red button to activate the recording. With an hour's record time and 1 gigabyte of memory, I knew I could let it roll on. But would I have the nerve to point it at the armed guards at the checkpoint we wanted to film? Holding the phone by the screen and the lens towards the gunmen, I stepped out from behind the car and tried to nonchalantly strike up a conversation with our producer while carefully aiming the phone. It worked. We got exclusive pictures of the underground bunker where Iraq's new government had allegedly been torturing its citizens.
