Siri on iPhone 4S lets you use your voice to send messages, schedule meetings, place phone calls, and more.
Ask Siri to text your dad, remind you to call the dentist, or find directions, and it figures out which apps to use and who youâ€™re talking about. It finds answers for you from the web through sources like Yelp and WolframAlpha. Using Location Services, it looks up where you live, where you work, and where you are. Then it gives you information and the best options based on your current location. From the details in your contacts, it knows your friends, family, boss, and coworkers. So you can tell Siri things like â€œText Ryan Iâ€™m on my wayâ€ or â€œRemind me to make a dentist appointment when I get to workâ€ or â€œCall a taxiâ€ and it knows exactly what you mean and what to do.
