To begin with, Siri is available on more devices. With iOS 6, it's available on the iPhone 4s and iPhone 5 (of course) as well as this year's Retina display iPad and fifth-generation iPod touch.

Siri can give you quick access to restaurant information.

Like before, Siri still requires an active Internet connection, but it now has access to more databases. As a result, Siri can now handle new topics. allowing the iPhone to answer your questions regarding movie times at local theaters; questions about actors, directors, movies and ratings; and questions about sports scores, standings, team schedules and player stats. Siri can also help you find and reserve seating at local restaurants. (To actually book seating, Siri launches the OpenBook app.)

Want more? You can use Siri to get spoken directions to any destination. Tell Siri to "Plot a course to the closest highest-rated Italian restaurant" and she'll navigate the best route and narrate directions in real-time (see below). She'll even answer questions like, "Are we there yet?"

Not enough? Siri can now launch apps by voice command, which is really useful, and can post status updates to FaceBook and Twitter. If you're looking to explore Siri more, you can use.
