Today i went to the apple store and had an apointment with the genius bar... i told the genius about my phone having cracks, and he looked at it but kept on saying that he couldnt see any cracks. he even took out a magnifying glass thing and couldnt see it.(i personaly couldnt see it too with the magnifine glass but it was really easy to see under regular light) the guy offered me a phone that came out of a white box, and i examined it.. and it also had cracks on it. I asked if he could open another one, but he said that they cant go through a whole inventory of phones... so i decided to just keep my phone for now, and try again sometime else. He said that anything that is mass produced will have some minor cosmetic problems, and its really hard to find a perfect phone... I also asked the genius if hes seen other phones crack, and he says hes only seen some that are right out of the box, and that have cracks that acually split the plastic. Another thing he mentioned was that if it was another different genius, they might have said that its not a problem at all and theres nothing wrong with my phone... so i was not as lucky as most of you guys that got to exchange your phones.. but ill try again.. but i dont know when i have to time. ill be sure to update you guys on it.
