The iPhone 4S is here! If you're waiting in line or impatiently by the door for the delivery guy to show up, you've probably got some time to kill. Maybe you should start thinking about a nice case to keep your brand new iPhone 4S protected. Word to the wise: if you're upgrading from a 3GS, it's a whole new ballgame when it comes to form factor and sensitivity. Protect your new investment accordingly (I'm talking to you, "butterfingers").
