I just took a look at the video, impressive but not the whole story.
First, I agree it did break from 9000 feet.
Second, you say it only broke the screen....looking at it I would say it did a lot more damage than "just broke the screen"
Third, yes it made noise but there was no indication or follow up that the phone "actually works", just him saying after hearing sound "It works, it works still".
Nothing on the screen and no follow up to confirm that the phone was operational. He did mention later that it could possibly repaired....
And lastly, the phone had tape wrapped around it. This may have prevented it from splitting apart at the seems during impact.
