A new report suggests that Apple’s next flagship handset, tentatively dubbed “iPhone Edition,” will feature a polished stainless-steel frame (similar to the Watch) and an all-screen front with curved glass. It is also said to incorporate a vertically aligned camera for shooting in VR. Is going from aluminum to stainless steel a good decision? One of the latest prototype designs includes symmetrical, slightly curved glass on the front and the back. The curves are similar in shape to those on the front of the iPhone 7. The new OLED screen itself is flat, while the cover glass curves into a steel frame. The design is similar conceptually to the iPhone 4 from 2010. An earlier prototype design had a thinner steel band, leaving more noticeable curved glass on the sides. Apple also tested a more ambitious prototype with the same slightly curved front and steel frame, but a glass back with more dramatic curves on the top and bottom like the original iPhone design from 2007, one of the people said.
