If your the kind of iPhone user that gets scratches on your iPhone's chrome back and edges, but not typically on the touchscreen than the SHIELD Apple 3G/3GS Polycarbonate Slim Fit Case is what you need. But this case does more than protect the chrome of your iPhone it also helps you grip the iphone much more securely so you're less likely to drop your iphone and it is less expensive than the Otterbox at only $8.99(for most colors) - $9.99(for a few other colors), but it doesn't have the drop protection of an Otterbox. The Shield case is very slim and while covering an iPhone it fits easily into your pocket. The Sheild works well with clear touch screen protection like the iKross Premium Reusable LCD Screen Protector for fuller protector.
