This might not be the answer you are looking for, but I really liked the Incase Frame case in the beginning. I had first gotten the green case. I used it for about two days and then noticed that it was denting my iPhone's back and at first, I thought it was something else but I have heard several accounts of this happening, from people I know, to reviews on the Apple website.
I stopped using the case thereafter.
One month later I decided to get an orange one thinking that it was just the other case that was weird. It was great for the first day also. Second day I see a white dot. Third day, the white dot turns into the case peeling. Now, the bottom is completely peeled and the case is turning very dirty, black around the edges. I assure you that I didn't drop it.
This is just what happened to me but like I said before, I really liked the case at first but it has problems that have to be fixed. I will definitely be calling Incase ASAP and telling them what happened. I really trust Incase and now my phone is damaged and each $35 case is too.
