Hi, I've noticed that on the blue background in the toolbar, and sometimes in the keyboard there is, for lack of a better description--a reticular gridlike pattern visible. It's almost as if there is a vibratory pattern visible at times, esp if after scrolling or popping up the keyboard. I looked at my iphone 4 and there is no such thing. I only now seemed to be noticing it. My keyboard in the app store also displayed that tearing that everyone is talking about.
