remove pic in quick setting grid In the "quick settings" grid you get by pulling down the right-hand end of the notification bar, the top-left item is a photo. I'd like to edit or remove this photo, but when I tap it, it says "The contact doesn't exist."

How can I edit or remove this photo?
Go into the People or Contacts app. At the top of the list is a heading Me with a special item to Set up my profile. Click that item and it takes you to the "New contact" screen. On this screen, to the right of the "name" field, there's a little grey "contact icon" box. If you click that you can replace the photo with a picture from the Gallery or by taking a photo.
