I played with the iPhone 5 at an Apple store. It has this little circle icon (greyish colored) on the lock screen (before slide to unlock), and also on the screen once it's unlocked to see all the apps; it I touched it there's a menu for Home, Siri, and iTune or something else I'm I'm not sure. I should have tried to ask a genius but they were all busy. Anyone know what that is? Also, you can drag and move the icon almost anywhere.
