ReadyCase

App-wise, an iPhone is like a Swiss Army Knife, but save for the flashlight it falls short in the physical world. Gear up with ReadyCase, a 3mm thick snap case that adds tons of versatility to your phone, including a headphone clip, magnetic quick-snap ring for interchangeable camera lenses, 8GB/16GB USB drive, plus a multi-tool with a bottle opener, serrated blade and screwdriver. Best of all, each pledge ships with both an iPhone 4/4S and iPhone 5 case body.
