“The image shows two iPod touch 4G cases with openings in the rear clear plastic for a camera and either a flash or microphone,” Starrett reports. “Notably, the shape of the cases suggests the touch will retain its curved rear shell design instead of moving to a flat back panel as seen on the iPhone 4.”
Starrett reports, “The two supposed iPod nano 6G cases, on the other hand, appear to be made for a squarish device based on the 1.7-inch Apple-branded touchscreen seen in photos earlier this year, without any room for a front-mounted Home button… Text accompanying the image notes that it is unclear what a move to this small a form factor might mean for the future of the iPod shuffle, though the “nano 6G” device is more like a screened iPod shuffle than the nano.”
