Face detection only for the 4s?

I have upgraded to ios 5.1 and haven't noticed any change in my cameras ability to "face detect". Is this feature for all devices or just the 4s?

Don't you have to get the app called klik ?

Face detection works fine on my 4S with no extra app to install

Clip from a website review of iOS 5.1:
4. Face Detection - The latest camera face detection now highlights all detected faces. So, with the latest iOS 5.1 on iPhone 4S, the camera app now will highlight all faces that it detects when the user is trying to snap an image.

Right, but not on the iPhone 4? Kinda disappointed, but I guess I understand since they upgraded the camera from the 4 to the 4s..
