Re: The real question mark is over the Supply Chain
Which do you want ? To have your cake or to eat it.
Either the phone is properly designed to be robust and damaging it in the way /demonstrated/ requires deliberate intent and concerted (not to say exerted) effort, OR the phone is able to be damaged in this way through carelessness in a way that Apples claims is not possible (which testing appears to support - /for those units tested/).
i.e. you just made exactly my point again. Something doesn't add up and variances in the quality of the manufactured units is at least an /explanation/ which excuses and deflections do not otherwise provide.
