Updated to GB and now I notice something wierd when I am in certian apps. I have noticed it in Email, stock web browser and the Facebook App. What I am seeing is that when you are at the bottom or top of a page and continue to pull up or down it it looks as if a faint see through blue color will show up on the bottom or top 1/4 of the page depending on which way you are using the phone. If i am in my email and scroll to the top and a see my first email, if i slide my finger down across the screen and if their is another email above it that is when I see it at the top of the screen. Has anyone else noticed this and what would be causing it??
