While walking the mean streets of Chinatown I found one of the coolest iPhone cases out there. The iPhone Cassette Tape Case. I realize that this will be lost on most kids today who have no idea what a tape cassette is since it has gone the way of eight track and records. Oh well, being old I think it is pretty cool. This iPhone 4 case is made of a protective silicone and looks just like an old cassette tape. You can buy them for around $7.99 here.
