When we were breaking down the meaty differences between the old-school 3G and the 3G S yesterday, we made an assumption about support for OpenGL ES 2.0 3D graphics APIs in the original iPhone 3G based on the fact that it had been available in the iPhone OS 3.0 SDK for several betas.

OpenGL ES is the lightweight version
