Can anyone post a picture of dust under their screen? It seemslike my screen's looking less clear and vivid than it usalky has been. I'm not really sure what dust would look like if it got under the screen, can anyone post some pictures of their's? I have a small opening between the metal and the screen and yesterday was the first time I kept my iPhone 3G in my pocket without a case. My screen looked great before I kept it in my pocket for a few hours, but I can't tell if there's dust between the screen...
