I made a reservation at the genius bar to get my iPhone 3G replaced because of a few stuck pixels, and a few specks of dust under the glass. The Mac Genius went and got a new one for me from the back, and after activating the new phone, I noticed that there was a big piece of dust under the glass again. But this time it was right in the middle of the screen. So the Genius went back to get another iPhone, and this time he let me check it first. I noticed that the screen was slanted (the left side is higher than the right side), and the wake/sleep button is also slanted, and once again there is one stuck pixel. When I told the Genius about this, all he said was "Well I can't go opening every phone for you." So basically he told me to deal with it, and I ended up taking that phone. Should I go in another Apple store and get a replacement? Because the slant in the glass gives a tiny gap between the glass and the chrome part.
