Apples parts suppliers are expected to begin mass producing displays for a larger iPhone as early as next month in preparation for a fall launch, reports Reuters. Reuters reiterates that two iPhones are coming, though it notes that mass production on the larger of the two iPhone screens may be delayed over production issues. Its unclear if this means that Apples reported 5.5-inch iPhone will not launch this year, or if Apple simply plans to prepare smaller quantities of it and is therefore able to start its production later. In January, The Wall Street Journal reported that the larger of the two upcoming iPhones was still in preliminary development, while the other model was already preparing for mass production, so its also possible that Apple does not intend to launch the new phones simultaneously — though no reports have suggested either way.
