Ericsson grip of death - iPhone not the only one

Shows a Test phone TEMS Ericsson K800i test phone (cost 2500+ Euro) being given the grip of death. A test done in a few minutes. It shows at a given point up to 16 dB losses by being held tightly as I have seen people doing it on the new iPhone.
Not saying the iPhone could not have a problem, I don't own one. But the iPhone is not alone for sure on this one. And Apple's latest explanation seems pretty valid to me
