iOS 6: Improved Siri and new calling features

Siri has been updated and now offers a whole lot more advance features and better information. Also, the moment you have been waiting for, yes Siri is now available on the iPad. Siri can now fetch you sports info and you can ask for almost anything from schedules, scores, player stats, team records, etc from the world of baseball, basketball, football, soccer, and hockey.
One of the biggest new upgrade to Siri is the ability to update your Facebook or Twitter status. Now no more tapping and all talking.
Now when you get a phone call, you can now quickly reply via iMessage or a plain SMS. Also there are preset messages that you can use to reply to the person calling.
In case you get a call and you can’t pick up the call right away, you can simply set a time based or location based reminder. You will get an alert reminding you about the call at a later time.
If you are really busy or just don’t want any phone calls or notifications, then there is the Don not disturb feature. This feature suppresses all incoming calls and notifications. Enable it manually or schedule a recurring time, like after 10:00 p.m. on weeknights. You can also filter calls and notifications from your favourites or specific contact groups.
