This is sorta similar to the time Nokia faked the PureView video during the L920's launch (happened seven years later obviously).<p>Also, I remember reading about some iPhone engineers that hardcoded the network signal indicator to show full strength during the launch of the first iPhone. Guess it's worth the risk since the media drops it after a while even if you do end up getting caught.
This was publicly admitted by Bill Gates himself in his joint interview with Steve Jobs. Just pointing out that it's not been a secret act. It made practical sense because of the nature of the Xbox360 processor architecture (triple core PowerPC).
