In line with a fresh report from KGI Securities analyst Ming-Chi Kuo claiming that Apple will be updating the iPod touch later this year with an "all-new" design using the same in-cell touch display technology rumored to be used in the next iPhone, Japanese blog Mac Otakara reports that Apple will also be moving the iPod touch to a 4-inch display from the current 3.5-inch display. Apple is otherwise said to be basing the iPod touch's internals on the iPhone 4S, although the case will include a "buffed aluminum" rear shell rather than the glass back of the iPhone 4S or the mirrored stainless steel of the current iPod touch.

It is, however, currently unknown what the function of the hole will be. Article Link: Apple to Update iPod Touch with 4-Inch Display, A5 Chip, Buffed Aluminum Rear Shell?
