SIRI (The Intelligent Assistant)

SIRI(The intelligent assistant) is one of the best features of iPhone 4s for me that makes it special, and one of the best latest phone released  in the market. Siri understand what you say (Talk to Siri as you would to a person), Siri not only understands what you say, it’s smart enough to know what you mean, it helps you do the things you do every day (Ask Siri to text your dad, remind you to call the dentist, or find directions), it has so much to tell you(When there’s something you need to do, just ask Siri to help you do it). iPhone 4S comes in 16GB, 32GB, and 64GB models, priced at $199, $299, and $399 with two-year contracts, respectively. They’ll go on sale October 14 in seven countries, including the U.S. Pre-orders will be available on October 7.
