You know Apple only charges $30 to replace the back glass of an iPhone 4 right? I hope you didn't get a 4S just because of that....

 

I use this skin on the back of my 4S by Karvt. It's real wood and wears nicely over time. It really give the iPhone a more organic feel, plus I hate seeing the fingerprints all over the back. I use a BodyGuardz film for the front. Never had a single scratch. I used a case for a while, but it was just too bulky. I figure, I'm paying for this design, why not enjoy it the way it's meant to be?

 

Actually decide to go without a case. The design itself is pretty awesome. Its lighter now and feels good in my hand without the case. This is what I took off.
