The iPhone 5 rumor mill continues to churn, with the latest speculation centering on what kind of glass will be used on the phone's cover. New reports suggest that Apple will use curved glass on the phone, similar to the type of glass used on a previous version of the iPod Nano.
That report comes courtesy of DigiTimes, which says that Apple "reportedly has purchased 200-300 glass cutting machines" in order to speed production.
A curved glass screen was used on Samsung's Nexus S smartphone, Wired.com points out, noting that such a screen can "improve comfort and perceived usability."
