Look, we're not saying this means anything, but the above rendering from iPhone case-maker XSKN sure does look like those supposed design changes we've been hearing about. You'll note the larger, more curvy back, space opened up near the earpiece for the rumored front-facing camera, and what appears to be a non-recessed headphone jack. Sure, this could be a ploy to get eyes on their pages, but even if they're citing the specs we've heard, this is still the first case design we've seen for anything other than the original iPhone.
