Apple is looking at various changes to its iPhone lineup over the course of the next year, according to a new report from Reuters, including two sizes of larger smartphone devices, in both a 4.7-inch and 5.7-inch flavor. The “phablet” plans are also being considered alongside a less expensive iPhone model, which is slated to begin production next month, according to Reuters’ sources, after a brief delay as Apple attempts to get the colors right for the new plastic-backed device.
