I don't doubt that they all come from the same place in China or wherever. But like you said my main concern would be whether that's an actual image of the case. If the actual case has the back cutout that off-center to compensate for the flash, it just seems ridiculous. Likewise all I really want is a clear case but if it looks bad I'm not going to throw money at it, even if it is just $5-6 dollars.
EDIT: I'm no longer waiting for this case, I took it up with my credit card company and already got the charge reversed. What I ended up doing was just ordering another cheap case that I might have by Saturday and it will serve the overriding goal of just protecting the phone until the custom one I ordered arrives.
I'm not fussy. So the cutout doesn't bother me if it off-center, upside down, vertical or whatever or if the case has a scratch or a rough edge. No one but me will look at it and if anyone else does they won't care about the centering of my flash. I just want to be able to see the Gelaskin back with a photo of my Grandkids through it. It makes me smile. I'm really not that "involved" with the phone other than to play solitaire and listen to a few podcasts.
