Taiwan-based component suppliers are beginning to prepare materials that will be assembled to build Apple’s upcoming iPhone 5 and iPad 3 devices, DigiTimes reports. The report goes on to state that Apple will unveil its fifth-generation smartphone and third-generation tablet in September ahead of launches in October. Details on the devices were scarce in the report, though it was mentioned that Apple’s next iPad may be even thinner and lighter than the current iPad 2 model, and it may also include a 250dpi display.¬†DigiTimes cites anonymous industry sources in claiming that Apple intends to begin low-volume production of the iPhone 5 in August, and production will then ramp up in September. IPhone supply volume is expected to total 24-25 million units in the third quarter, 6-7 million of which will be the new iPhone 5 model. Total iPhone volume for 2011 is expected to reach 85 million, and DigiTimes says iPad volume may break the 40 million-unit mark.
