When searching through the App Store and you find an app you like so you download it, at the moment you download it, you get a pop up to enter your Apple ID password so you do. When you enter that password and tapped the "123" button to put in the number along with the password, do you guys get a thin multi-colored line flickering in the middle of the keyboard? This happens every time with me. Please give it a try by downloading a free app and see if this is not just my iOS 6 being weird. I tried to take a snapshot but it never captures it because once I take the snapshot it stops. Very weird.
