Apple has made another subtle change to its iOS App Store, dropping the "Game of the Week" and "Staff Favorites" sections on the main page in favor of "Editor's Choice" and "Free App of the Week." The new designation has kicked off naming Chillingo's new Air Mail game and Autodesk's SketchBook Ink drawing app for the iPad, and Facebook Camera and Extreme Skater getting the nod on the iPhone. Cut the Rope: Experiments is the free app for both.
