6. OtterBox Impact
The OtterBox Impact ($14) is a silicone rubber case that adds additional shock absoprtion via an extra X-shaped layer of silicone that covers the iPhone’s impact points. Despite the extra padding, the case is still quite pocketable, although not as slim or lightweight as most silicone case. A drawback is that the case cannot be used with most iPhone docks with the exception of the wider-mouth Universal docks. The Impact is available in black or white and comes with a screen protector and cleaning cloth.
7. OtterBox Commuter TL for iPhone 3G/3GS
The OtterBox Commuter TL case ($22) walks the line between the two worlds of protection and slimness. It’s a two-part case featuring an inner soft rubber layer and a plastic hard-shell outer layer. The silicone layer is left exposed along the edges of the iPhone for superior grip and comfort. Despite the two layers of protection, the Commuter TL is surprisingly thin and pocketable.

8. Trexta Leather Racing Series Case
The Trexta Leather Racing Series case ($30) for the iPhone 3G/3GS is a hard-shell case covered with stitched leather.

11. JAVOedge Cork Back Cover for iPhone 3G/3GS
The JAVOedge Cork Back Cover ($20) is an innovative rear case for the iPhone 3G and 3GS that crafts its unique look by affixing a layer of shredded cork to a hard-shell layer. The case offers better than usual protection from accidental drops and offers excellent access to all of the iPhone’s ports. But the main selling point is its love-it-or-hate-it style. Some downsides are that the cork does not offer uniform coverage—there are tiny gaps in the cork where the back of the iPhone peeps through. The case does not ship with any accessories.
12. Griffin Clarifi Case with Built-in Close-Up Lens for iPhone 3G
The Griffin Clarifi Case ($25) is a “sliding” case, meaning the bottom half slides off allowing for worry free access to the dock port and speakerphone functionality. But its most distinguishing feature is a macro lens that, once slid in place, allows you to take clearer pictures of close-up objects (objects a few inches away). It also offers the best protection of any case for the iPhone’s camera lens, whose exposed location leaves it susceptible to scratches and fogging effects in pictures.

The case is made of two pieces that snap together, encasing the iPhone. It does not come with a front screen protector–a minus or plus depending on who you ask. The clear case is a solid compromise for those wanting protection but also liking the original appearance of the iPhone.

15. Contour Design Hardskin for iPhone 3G
The Contour Design Hardskin ($22) is a hard-shell case that, similar to the Countour Design iSee, has two pieces which snap together to form the outer casing. The Hardskin’s curves match those of the iPhone 3G’s body, so there is no loss in the iPhone’s form factor when covering it.

17. Core Cases Aluminum Slider Case for iPhone 3G
The Core Aluminum Slider Case ($30) is a rare metal case for the iPhone–rare because metal can interfere with the iPhone’s cell reception. The case is made from aluminum, which doesn’t block signals as bad as some metals do. However, some do report a slight hit on their reception, so if weak signals are a problem for you, this might not be your case. Still the Core Aluminum case is one of the better looking cases out there (especially in silver).
