There's very little you can add to an iPhone to make it better but the Griffin Reveal case is a great little piece of kit. It offers much needed protection from the elements as well increasing your grip on the phone thanks to a very small, subtle, ruberised edging. The clear back is perfect for showing off your new gadget and all of the phones vital access points and buttons are accesible with ease.
As great as the iPhone is I always had the feeling that I could drop it at any given moment as it's such a shiny (slippy) piece of kit. This case is the perfect solution as it adds minimal bulk and lots more grip in the hand. You'll hardly even know it's there after you've had it on the phone for a few days.
It is more expensive than a lot of options on the market but I've tried quite a few different cases in the past and this one is head an shoulders above the rest.
