Do iPhone 4 And 4S have Siri Or Just 4s

Both have Siri. Iphone 4s just has better tech, same programming and apps though.

Only iPhone 4s have Siri. If you have an iPhone 4 and are looking to buy a new iPhone 4s, its not worth it. In my opinion, There isn't that much difference.

Only iPhone 4s has Siri iPhone 4 has voice controll instead but it's not a good app like siri
