did you order the 4S cases, found here: http://www.desmay.com/collections/iphone-4-4s/products/the-slight-0-35mm-iphone
I think they liked the iPhone 5 cover to the 4s order link by mistake when it was originally listed. I know I ordered the case for the 5 and they said they are sending me the case for the 4s. Now I have to exchange it.
