Production of the next iPhone has already begun, a Japanese-language Apple blog claims.
And to back up its claim, the Macotakara blog cites listings for iPhone 5 cases on China's Alibaba.com.
The blog goes on to say that the back of the new iPhone has both glass and aluminum. "In the area where aluminum is not used, there is glass." (see image below).
This contrasts with previous reports that claim the next iPhone will have an all-aluminum back like the iPad.
By comparison, the iPhone 4S sports glass coverings on the front and back.
The iPhone 5's most anticipated feature -- which has been widely reported -- is a larger 4-inch class Retina display with a 16:9 aspect ratio. Previous iPhones have had a 3.5-inch display with a 3:2 aspect ratio.
Oh, if you're interested in preordering an iPhone 5, Chinese resellers on Taobao (a unit of Alibaba) are already accepting orders, according to Reuters. Good luck with that.
