Images of an alleged rear shell for Apple’s second-generation iPad Air were posted on Weibo this weekend. The images show redesigned speaker holes containing one row of large openings instead of two rows of small ones, as well as recessed volume controls. Also, the microphone has been moved away from the top center of the device to near the camera lens. Though the changes are certainly possible, it’s worth noting that they would necessitate changing most iPad Air cases, including Apple’s own iPad Smart Case. [via Nowhereelse.fr]
