Siri. The intelligent assistant that helps you get things done. All you have to do is ask.

Now you can use your voice to use your iPhone 4S. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.
