Siri on iPhone 4S lets you use your voice to send messages, set reminders, place phone calls, and more.
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. Just talk to Siri as you would to a person: “Remind me to call mum when I get home” or “Do I need an umbrella?” Siri not only understands what you say, it knows what you mean.1 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.
