There seems to be little to no information or examples on using OpenGL on the iPhone. I’m currently working through OpenGL(R) SuperBible: Comprehensive Tutorial and Reference (4th Edition) and translating the examples to work on the iPhone as I go.
So far I’m partway through chapter 4. I’ll upload more examples as I complete them. Here is the source code for examples 2.1, 2.2, 2.3, 3.2, 3.4, 3.8, 4.1, 4.2 iPhone OpenGLES example code, 2.1 through 4.2, 4.3 Planets, 4.7 SphereWorld.

I recently met Ashley Mills on Twitter who is also working through ‘The SuperBible’ and converting examples to work on the iphone and posting the source for you.
