After confirming an incompatibility between the iPhone 4S and China Mobile's SIM cards last month, Apple has now fixed the issue, according to China Mobile.
The issue was in iPhone 4S's GSM chip, which only supported the P frequency band (885-915MHZ), but not the E frequency band (880-890MHz), China Mobile explained.

The problem has now been solved, and all devices manufactured after Feb. 8 fully support China Mobile's network.
For customers who bought an iPhone 4S before that date and are using China Mobile's network, Apple may release a China-specific iOS update in early March to resolve the signal problems.

While this issue may not seem very interesting to those of us outside China, it is definitely a serious one for Apple. China Mobile is the world's largest mobile operator with more than 650 million subscribers; although it is not yet officially a partner of Apple, rumors say this might change in the near future.
Recently, Apple CEO Tim Cook pointed out that China is a very important market for Apple, and Morgan Stanley’s Katy Huberty predicted that Apple could move as many as 40 million iPhones in China in 2013.
