Apple is planning to use curved cover glass in the iPhone 5, according to a new report. Citing industry sources, DigiTimes reports that cover glass makers are typically reluctant to purchase the required glass cutting equipment due to the high capital involved. In order to push the production forward, Apple has reportedly purchased 200-300 glass cutting machines to be used by the glass makers. The sources also said that the machines are currently being stored at associated assembly plants and will be brought online once curved glass yield rates reach a satisfactory level. Notably, the Samsung Nexus S, Google’s most recent flagship Android device, features a curved display.
