Cases and dirt? Hi all, New here,greatforum. My Q should arrive sometime nexted week and I have been reading reviews and your coments about alot of cases. I have looked at the mobi clear and other ones of that type and have a question about them. Have any of you experienced any dirt getting up under the screen protector and scratching it up? The reason I ask is I have an Ipod soft case and over time I found that little particals of dirt have gotten in it and have begun to mark up the screen abit. I am really anally retentive about my toys and like to keep them in good shape.
