Original iPhone 4 Cases MAY NOT fit your new iPhone 4S-Read Why
The iPhone 4S from the photos Apple has posted on it's site is the verizon design-that means that the buttons and ringer switch have been moved down ever so slightly, So unfortunately like with the original iPhone 4 cases that could not fit the new button layout of the verizon iPhone 4- so NOT ALL iphone 4 cases will fit the iPhone 4S unless there universal or have a open side for the buttons/ringer not fitted for the orginal iPhone 4 design.
