I have to admit, when I see someone trying to intentionally bend a brand new ipad or iphone, I cringe. I think of all of that $700 going to complete waste.
I don't see the point in watching them myself. The amount of ad revenue the poster gets from the videos probably more than covers the cost of the phone.
They probably bought AppleCare prior to doing the tests. So they'll probably just pay the 79 dollars or whatever the accidental damage replacement fee is at the Apple Store. Their views are probably worth more to them then the 80 bucks.
