Reporters at Reuters are now kitted out with a N82 which allows them to take pictures, shoot video and (crucially) upload it all onto a website while on the move. Having trialled it at Davos, Jeff Jarvis concluded: "a wired journalist without a camera and connectivity is like a hack without a pencil". All journalists, he said, should be "mojos" – "mobile journalists".

The key though is connectivity. Jarvis trialled his phone in Switzerland, a country awash with broadband and wifi connections. Trying to do the same in, say, eastern Chad is not as straight-forward.

David Axe, a self-styled war correspondent, experimented with a N95 and a website called Qik on a trip there in June. Footage shot on his phone was supposed to upload immediately to the Qik site. Except places like eastern Chad don't have the world's greatest internet connections. He managed to upload a single one-minute film in a month-long trip: "In theory, it was perfect for the solo freelance war journalist. In practice, it's far too fragile a system for remote field work," he said.

And that's the problem. The sort of place where this sort of technology would be most useful is likely to be the sort of place where it won't work. Still, the days of reporters going out to work with just a notebook and pencil are long gone. As are, I've now realised, the days when all you need a phone to do is make calls. We're all mojos now.
