OtterBox iPhone 4 Commuter Series Case
OtterBox products aren't always pretty, but you'd be hard put to find cases that better protect your mobile devices. This is true of the company's $34.95 iPhone 4 Commuter Series Case, which is probably the bulkiest, yet most protective case featured here. It comes only in black, but offers three layers of protection, including a screen protector.
