Though many expect the next iPhone to look similar to the iPhone 4, a new rumor from DigiTimes suggests that a future version of Apple's iPhone (perhaps the iPhone 5, perhaps the "iPhone 4S") may feature a significant design change.
DigiTimes's "industry sources" with knowledge of the supply chain claim that Apple's next handset will feature a curved glass display.
"Cover glass makers are reluctant to commit investment to the purchase of glass cutting equipment due to the high capital involved," the sources said.
DigiTimes also writes that Apple has purchased between 200 and 300 glass-cutting machines, but notes that the company is still working out a production timetable with suppliers and manufacturers. Earlier rumors have hinted at a September release date for the next iPhone.
No word on whether the "curve" will give the phone a more ergonomic feel, like that of the slightly concave Samsung Nexus S, or whether it will resemble the convex display of the previous generation of iPod Nano devices.
