Some people have clear cases and the camera part generally shows in all cases. That said I've had iPhones since the first model and never had a case. (I did break one but that was because I tripped and while I didn't drop the phone I did use my hand to break the fall and just hit the phone on the edge on the concrete)
I really hope the Pro models finally come in some bold colors. Just give me the same options as the back side of the iMacs. I'm so tired of these dull, dark colors. By all means keep the "starlight" and "midnight" for people who want a boring choice but if you're going to offer a color option, actually offer some color.
I kind of have my doubts about this one. The imperfections seem like something Apple wouldn’t do in production. You really see them with the green phone in picture 4. Perhaps these were color test prototypes.
