How to tell the difference between an Iphone 4 and Iphone 4s?

Question

Ok can someone give me the step by step way to tell the difference between 4 and 4s? Everyone's giving me different answers.

For instance, on the back my phone says model A1332 which some people say means its an Iphone 4 but it also looks like the phone on the left in this image: http://iphone.mythailandblog.com/wp-content/uploads/2011/10/compareiphone4s.jpg which they say means its 4s.

Anyone out there able to tell me how to find out for sure?

Thanks!
