"Next up in our series of iPhone case reviews is the OtterBox for iPhone Defender Series. OtterBox is well-known for offering extremely rugged, often waterproof cases for everything from laptops to smart phones, PDAs and iPods. The Defender Series is touted as having bump, drop, and dust protection, and, while not waterproof, will provide protection against rain and other precipitation. Otterbox also has an Armor series for the iPhone, which is even more rugged: completely waterproof, dust-proof, and drop-proof."
