A couple of weeks ago, Apple's launch of the iPhone 4S in China descended into chaos: Apple Stores didn't open on time, unhappy customers threw eggs, and eventually, a SWAT team was called to the Beijing retail store. According to Business Insider, during yesterday's financial conference call Apple CEO Tim Cook acknowledged that the company had underestimated demand for the iPhone 4S in China.

The launch of Apple's iPhone 4S in China descended into chaos yesterday, as intense crowds punctuated with professional scalpers forced an Apple Store in Beijing to postpone the handset's launch.

Though it was only recently announced that the iPhone 4S will launch in China on January 13, China Unicom has already decided how its going to sell Apple’s fifth generation handset.

In a press release that recently hit the Web, Apple has announced that it plans to launch the iPhone 4S in China and 21 other countries this January 13.

Apple's iPhone 4S handset is now available to purchase in 22 countries around the world.
