Do you think it's possible that Apple fakes such competitor tests?
We know nothing about the presets used for producing this video.
Which phone cell was the phone connected to and was this cell sending in constant signal strength?

As far as I have heard about Steve Jobs former activities and strategies (some say intrigues) to get what he wants I think we have to include the possibility that this videos are consciously fakes.

Apple in my eyes turns more and more into a market player of very doubtful image...
Why? Because Apple's the one who do not shy away to lie to it's customers and extremely negatively patronize all their matters, who demands 2x and 3x overpriced from their customers, who handle it's problems with lying and pointing a finger at the competitors to hide and underplay own problems.

Even they would make better products because of the reasons above for me Apple is clearly out of the question and I doubt everything they state.
