The iPhone 4S' Siri integration may be a potential game changer, but she's not quite the world traveler some of us would like her to be. In fact, it seems she's as lost outside of US borders as any unprepared tourist. Looking for a pub in London? Better find a traditional map. Need to know the time of day in Canada? Siri admits she has no idea, go buy a watch. Business search (via Yelp), directions, and traffic data search all appear to be US-only features for now, and Wolfram Alpha only works in English-speaking countries. The automated assistant's international failings aren't too big of a surprise, however -- Apple's own Siri page outs the service as a beta, noting that some features may vary by area. Stuck with sub-par international support? Sit tight, it's coming: Apple's Siri FAQ states that additional language support (including Japanese, Chinese, Korean, Italian and Spanish), maps and local search content are set to go international in 2012.
Update: Wolfram Alpha works outside the US in English speaking countries, thanks to everyone in the comments for the clarification.
