If you've recently updated to iOS 7, you may be wondering why you can no longer swipe to the right off your Home screen in order to search for apps like you could under iOS 6 and below. No need to worry though. Apple hasn't removed the feature, they've simply changed how you use it to make it even more convenient and easier to access.
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.
