No, only 4S and new iPad
Siri was released on 4s just to have something new and apple wasn't ready for a big update on all devices. In October 2012, it will be released for the New IPad (third-generation) with iOS6. It will also be available for the iPhone 4s and 5, as well as the fifth-generation iPod Touch.
accuracy there is no app for Siri it is only available for the new iPhone 4s and can be accessed by holding down the home button. Siri is not available for the iPod touch iPad or older generations of the iPhone,
Well there is no such thing as IOS 6 yet. So far its IOS 5.1 i think and siri is only available on the apple iphone 4s. No other devices have siri and there is no app or update for it
