Other World Computing offers the HeadCase Bottle Opener Case for iPhone 4 and 4S, model no. DM01-4-B, for $7 plus $1.75 for shipping. That's tied with our mention from two weeks ago and the lowest total price we could find now in any color by a buck. This plastic case features a stainless steel bottle opener and can tab opener, and works with a free app that counts the tops/cans popped.
