Damages the back of the iPhone
Watch out for this case. I registered on MacRumors just to post this

. I had this case on for two weeks, noticed the major problems with hazing the flash on low light pictures, and had it pull up my skinomi skin, so I returned it. After that I applied a rear skinomi skin, but I saw that it had the same design as the diamonds.
So I took off the skinomi skin, which also distorted my pictures surprisingly, and noticed that the rocketfish case had left the diamonds permanently on the back of my phone.
It is really odd. I can wipe them away with my microfiber cloth, but then when you touch them again, they reappear. They are very faint, and you have to look for them like you look for scratches, but they are there, and they are there to stay it seems.
So I went in to apple. they said it was just dust and dirt that was constantly being pushed into the screen. They said it wasn't their prob, but BestBuy's. So I was about to return it to AT&T and tell them it wasn't durable enough since it is really BestBuy and Apple's problem. Then I would get a white one when they came out. However, I went to my BestBuy first and after a half an hour of them trying to figure out what to do, they told me to try at Apple one more time, otherwise they would replace my phone.
So, I am very disappointed with the Rocketfish product, disappointed with Apple, but very pleased with BestBuy's service.
I'd return your cases for this, and see what BestBuy can do for you. The smudges are small, and I don't know if it really is scratching or if the phone absorbed the oil from the gel or something, but if you are anal about your phone it kinda sucks.
