One of our AT&T (T) sources sent over a few images of iPhone 5 cases that are already popping up in the company’s internal accessory systems. The images we obtained feature the iPhone 5 in two different manufacturer’s cases, and we have one additional render that shows a new screen protector. If you remember what happened last year around the same time, we posted images of iPhone 4S cases that turned out to be authentic ahead of the “disappointing” iPhone 4S, which launched instead of the much-rumored iPhone 5. Separately, iMore — which has a solid track record with information regarding unannounced Apple products — is reporting that it has confirmed the new iPhone will indeed be in line with the countless leaks that have been floating around the internet. Read on to see the rest of the photos.
