If you need information, chances are Siri can help you find it. Apple currently enables Siri to search Google (or Yahoo! or Bing) for general information, and Wolfram|Alpha for computational knowledge. You can use Siri to find anything you would normally type into a web search box, only there's no typing needed. Just ask, and you'll get back everything from the latest celebrity gossip to the answers to that nagging math questions to a listing of the best free apps for your iPhone.
