Pegatron is gearing up to start mass-producing the next-generation iPhone, according to a report by The Commercial Times. Production of the next iPhone (or iPhones) is said to be starting in Q2, though there aren't many more specifics available, and no indication of just how many devices will be produced at that time. Currently not much is known about the so-called iPhone 6 aside from a few details about its display, which is said to be made of sapphire (possibly at Apple's new Mesa, AZ plant) and will be bigger than the current iPhone display. Some reports even indicate that there could be two new models with differing screen sizes, both bigger than the iPhone 5s.
