Back in April, we told you about a Nokia Lumia model codenamed Superman. The phone was rumored to feature a 4.7 inch screen, with a 5MP front-facing snapper designed for better quality "selfies". Today, some new information about the phone has surfaced. Expected to be a sequel to the Nokia Lumia 720, there are three product codes believed to be associated with the new device, RM-983, RM-984 and RM-985.
