Pegatron has received a greater volume of orders for the iPhone 4S than originally expected, Commercial Times said on Wednesday. Reportedly, Pegratron had originally expected to build and ship 10 million iPhone 4S units, but it is now serving an order for 15 million units, DigiTimes said. Pegatron could ship 2-2.5 million iPhone 4S units during the fourth quarter of this year according to the report. The Taiwan-based manufacturer hopes Apple will bless it with iPad 3 orders as well, and has supposedly boosted its ability to build the metal chassis required for the device.
