Siri is a built-in virtual assistant on Apple devices and cannot be downloaded separately. To access Siri, simply enable it in the device settings under "Siri & Search." On iPhones and iPads, you can activate Siri by holding the Home button or the Side button, or by saying "Hey Siri" if it's enabled. For Mac, you can access Siri from the menu bar or by using a configured keyboard shortcut.

The new iPad (3rd Generation) will get Siri when IOS 6 is released this fall.
