iFrogz Mix for iPhone 4/4S
When it comes to iPhone cases, we like the combination of rubber and plastic. iFrogz' new Mix for iPhone 4/4S ($30) uses both in a pretty simple design. The back is made of a very sturdy hard plastic in a variety of designs; some are translucent, while others have solid colors or prints. Around the edges, your iPhone is protected by pliable rubber with holes for all of the inputs and outputs. It's fully compatible with Universal Docking accessories.
