Preview at WWDC likely in June, followed by September launch.
'iPhone 5' Silicone Sleeves Already Arriving at AT&T Retail Stores
We now have evidence that cases for the rumored iPhone 5 redesign have already begun arriving at AT&T retail stores, as one reader has sent us alleged photos of iPhone 5 silicone sleeves that appear to have arrived at his AT&T store today. Like other cases for the rumored redesign of the iPhone 5, these cases appear to show a tapered design and the mute switch moved to the opposite side of the device.
Third-party cases continue to be essentially the only evidence in favor of a redesigned iPhone 5 even as evidence for the iPhone 4S continues to mount in the form of parts leaks, inventory database listings, and other reports from sources.
