Apple may emulate Google’s Nexus S with a curved screen for its next iPhone.

According to the report, Apple has bought between 200-300 glass-cutting machines to make a curved screen for the next iPhone to speed production along. Glass makers have reportedly been reluctant to purchase the machines themselves because of the high capital investment.

In its take on this rumor, Engadget said this could be a return to the iPod Nano screen, which curved out. But others, such as Apple Insider are speculating that Apple may be taking a leaf out of the Google design book and offering a contour screen similar to the one on the Nexus S.
