I am after a case for my iPhone 3G, but I want one that is the least noticeable and least chunky etc. Some kind of thin shell etc. The case that I am looking for is really intended to prevent scratches to the unit, rather than to absorb shocks if I drop it etc. Because I love the iPhone 'au naturel' and have been carrying it around 'naked' until now, but I have heard so many horror stories of people having theirs scratched and dropped etc! And the reason I dont like a big silicone case is because it doesn't do the iPhone's sleek design any favours. Your opinions (and pictures) would be most appreciated. Thanks in advance.
