The cases have arrived just a day after a screenshot leaked showing iPhone 5 cases from the brand Case-Mate in the AT&T inventory system. The cases in the photo are not from Case-Mate, but they clearly say iPhone 5 on the packaging and appear to be consistent with the rumored appearance of the next-generation iPhone.
It appears to be thinner and longer like many other leaks have suggested, possibly even the tapered design. You can also see that the mute switch has been switched to the opposite side of the cases, away from the volume buttons.
Now that cases have started arriving, maybe it is time to speculate on the release date of the iPhone 5. How close will it be to the October 4 event, a week? Or maybe that October 14 rumor will hold water and the new iPhones are only two weeks away from going public.
