I just read about this issue today here:

I've been debating getting an iPhone. But every time I get an Apple portable device (the iPod nano 3g was the worst with "tilted screen" problems) I end up having to deal with exchanges because of problems.
Now I'm hesitating again after reading this thread.
I've been developing iPhone apps with a friend (I must be the only iPhone app developer who doesn't actually own an iPhone!) and have been feeling the pressure to get one because there is just so much you can test in the simulator.
But I hate having to deal with issues like this, even if they are just cosmetic.
Are at least the screens ok? No tilts or broken pixel problems?
