Most Stylish: Speck CandyShell Card for iPhone 4S/4 ($39.95)
This two-layer case, available in six colors, masquerades as your typical iPhone case from the front, but flip it over and notice that it doubles as a wallet. Comfortably store up to three credit cards and folded bills in the back compartment—perfect for on-the-go types and light travelers. The rubberized slot ensures security, while the thumb release gives you easy access to your cards and cash. The hard outer shell protects your phone against impacts, while the soft rubber shell absorbs shock and guards the screen in the event of a screen-first fall.
Our tester said, "Most cases go one of two ways, too bulky or too flimsy, this case found that happy medium. I've dropped it with no problem and it's not a hassle trying to dig it out of my pocket."
