According to Digitimes, Taiwan-based Apple product manufacturer, Pegatron, has landed 15 million iPhone 5 orders from Apple. This is the same manufacturer that builds the CDMA iPhone 4. The report says that these 15 million devices are expected to ship in September, as we previously reported, and the upgrade will not be major. In addition, new “manpower” for factories has been hired to handle the iPhone 5 production load.

The next version of the iPhone recently reached its final testing stage and is expected to pack the dual-core A5 processor found in the iPad 2, an improved camera with an 8 megapixel sensor (possibly Sony-built), and a design akin to the design of the iPhone 4. There has been some debate as to whether or not this next-generation handset will be a minor upgrade or a major upgrade, but most sources have pointed to a minor upgrade; at least for the device’s exterior.

In addition, the next-generation iPhone is said to feature a dual GSM+CDMA cellular chip. This would allow Apple to product one handset that can connect to both CDMA (Verizon in the U.S.) and GSM (AT&T in the U.S.) networks. Additionally, there has been some talk about a T-Mobile variant of the next iPhone, with a next-generation T-Mobile iPhone reportedly being in testing (with an A5 chip!) and T-Mobile explaining the relative popularity of the device on their network.
