Quirky has made some of the coolest gadgets and off the wall products I have seen over the last few months. The latest product to come from Quirky is for the iPhone 4 and is called the Tilt.
The Tilt case has a flip down section that can be used to prop the phone up in portrait or landscape modes. The case is offered in black or purple/white colors and the thing is a bumper style case. It should keep you from blocking the antenna and help reception too.
The body of the case is plastic and the face is made from rubber. The indentions on the side are for wrapping your headphone cables around the case for storage. Quirky will make 990 of the Tilt cases and 32 are spoken for so far. You can pre-order one for $28.
