Some early iPhone Duo users report damage near the inner hinge and lines across the display. An Australian user quoted by The Verge says the screen broke after brief use and an Apple Store replaced the device. Other images have circulated, but incidence relative to sales, usage conditions and a shared defect remain unverified. One replacement account does not establish a universal warranty policy, and Apple had not provided a specific explanation. Early reports should be separated from conclusions about overall durability.
