What is the difference between the iphone 4 and iphone 4s other than price?

So i'm planning on getting and iphone 4 or 4s and i was wondering what the difference was

Siri
FaceTime
Front facing camera.

4s has Seri and you can take panoramas. Also the quality of pictures are a little better and it's a little faster.

Siri and FaceTime just get the 4s if I'm correct it's 50 dollars and just get the 4s

BOTH the iPhone 4 and the iPhone 4s have front-facing cameras and facetime

the differences is the iPhone 4s has a higher resolution camera (5mp vs 8mp), Siri, and a faster processor

Y'all need to learn how to speak better… The iPhone 4S has a faster operating system, you can FaceTime over 3g and the 4s has 4g and 4g LTE

You can compare the two on apple.com. Click on the iPhone tab, then scroll down until you see "iPhone 5 From $199" then below "compare iPhone models" It will compare the iPhone 4, 4S, and 5 for you. It compares everything from size and weight to apps it includes and then to capacity and price.

The 4s has Siri, a better camera, and its faster (I think)
