Outside of North America, China may be Apple's largest market. Although the iPhone 5 is set to be introduced by China Unicom and China Telecom during the first three months that the new smartphone is available, the biggest audience is still China Mobile's 700 million subscribers.
Now Apple watchers believe new technology quietly added to the iPhone 5 could improve the chances the iconic handset could soon be sold by the world's largest mobile carrier.
According to The Wall Street Journal, TD-SCDMA is supported in a Qualcomm chip found in the iPhone 5 when the phone was torn down by the folks at iFixit. The transmission technology is China Mobile's version of 3G and a clue that Apple wants the carrier as its third partner in the Asian giant. It's intriguing then that Apple doesn't mention TD-SCDMA in its technical specifications of the iPhone 5.
