Is this happening to all 600,00+ pre orders? I doubt it, Are the screen issues happening to all 600,000+ pre orders? Nope again.
So therefore when one removes the improbable what your left with is although unlikely the most probable issue. If its not happening on every single phone out there, is it possible that its a production issue? When mass produced any product can and will have issues.
Until every single person who pre-orders, or buys an iP4 has this these issues I don't think we can blame AT&T or Apple.
Nothing is perfect, Kids are born with birth defects, allergies and what not. What would have happened if the first kid/s born had birth defects? Would the human race just up and stopped having kid's because of a couple issues? I doubt it.
I could go on and on, like what about when you buy a bike for your kid and it is missing a screw (Insert smart remarks here), or when you buy a entertainment center and put it together only to find out all the pieces dont fit as they should? Does one then presume that all bikes and entertainment centers are crap and that you should no longer buy them?
Calm down, step back and re-evaluate the situation. For those of us with issues, I am sure Apple will take care of us and for those of you lucky enough to be blemish free, enjoy your new toy.
Ohh and as the Human Torch says "FLAME ON"
