Wireless data transmission...you know that 21st century technology that allows you to transmit data wirelessly. Just because we see video data being received wirelessly doesn't mean we can't transmit it--considering the guy wrote the app specifically to do this. Maybe if you actually do more research on this, you'll actually see what the guy did.
It's funny how I gave you all those links, proving you're wrong on the N900, yet you still can't face the fact that you're wrong. Instead you choose the one link that isn't fully explained in the video of 'how does it do it' so automatically you choose it as a basing point to strengthen your statement, even though you have already been proved overwhelmingly wrong by pretty much everyone counter-posting.
