iPhone's Siri Learning Chinese

Apple is about to get more than a billion new potential customers for the iPhone 4s—but many of them may find it tricky communicating with Siri just yet. The smartphone will be launched in China and 21 other countries next week, and while its voice-activated virtual assistant currently only speaks English, French, and German, Apple says it plans to add Mandarin later this year, the Los Angeles Times reports.

"Customer response to our products in China has been off the charts, " Apple CEO Tim Cook said, noting that the iPhone 4S will soon be available in more than 90 countries and regions, making it the fastest-ever iPhone rollout. Apple currently partners with the carrier China Unicom, but insiders tell Computer World that it is close to forging a deal with the country's behemoth carrier, China Mobile, which boasts a whopping 630 million subscribers.
