Siri is the cool intelligent voice assistant built into iPhone 4S. It can answer most of your questions and let you control the phone through voice commands.
As I said earlier, Siri is a software inside the iPhone. So,normally, you might think that, if you ask whats the best cell phone from Siri, it should say “iPhone”, right? Wrong! It said, Nokia Lumia 900! Why is this? Siri have a built-in feature to work with Wolfram alpha to get answers to your questions. If you ask Wolfram “What’s the best cell phone ever?“, it’ll say Nokia Lumia 900!
