Not without jail breaking it.
The iPad mini does in fact come with siri
Wait till this fall for IOS 6. Siri will then be available for the third-generation iPad (iPad 3).
Although the iPhone 4s introduced Siri, a Beta program with voice recognition, it was not ported to the iPad 3. The iPad 3 does have speech-to-text capability for creating emails, and you can use your iPad as a voice recorder, but voice recognition is not built in. Siri may be introduced for the iPad later.
The new iPad (3rd Generation) will get Siri when IOS 6 is released this fall.
the iPad 2's do not the all new iPads oriPad3s do.
Siri is not available for the iPad yet. When iOS 6 ships this fall, only the iPad 3 will get it.
No but it does have voice dictation witch is a feature from siri
You trade in your iPad 1 or 2 to the new iPad (3rd gen). Only that model has Siri.
it isn't.
You can't
No, at least not yet. Siri is only on iPhone 4s.
I dont think you can use siri only the iphone 4 can by holding the home button
