iPhone 4s camera into iPhone 4

It is highly unlikely that the new camera is compatible with the old device. They do have very similar shapes and sizes, and the connectors are in roughly the same place, but the chances of it working are rather slim. We aren't ones to discourage a little experimentation, though! If you have an extra iPhone 4S camera laying around (not sure how that happens, exactly) give it a shot and let us know how it goes. We even have a guide for it! Just know that none of us will be trying this on our phones, as we do not want to risk it.

Hope this helps! Good luck! We would love to see pictures or a story about your project!
