How to put my iPhone 4S hardware into a 3GS frame?

I like the 3GS frame way better, but I want the speed & resolution of my 4S.

Nope. The 4S uses external antennas around the edge and they have to go with the externals, plus a lot of other complications are likely to occur. They probably wouldn't fit anyway because not only it is a different shape, it also has a bigger battery, camera etc.

R u crazy? It's not possible
4s is more attractive & cool
