KGI Securities analyst Ming-Chi Kuo has said many times over the past few months that Apple's Tenth Anniversary iPhone due next year will move from the current unibody aluminum industrial design to an all-glass front and back plate sandwiched between a stainless steel frame.
In a new note to clients, a copy of which was obtained by MacRumors, Kuo explains that the reason why so-called 'iPhone 8' will switch from metal to glass for its casing is to support advanced wireless charging technologies.
