i have noticed that self.context is empty. On my ipad3, initWithAPI_(2) returns an object, but 3 does not.

also, see here http://www.raywenderlich.com/3664/opengl-tutorial-for-ios-opengl-es-2-0 Dont you need to set up a framebuffer, and also call presentRenderbuffer? Also note that you didnt actually call glClear in your code.
