Developers have received a new e-mail for the Apple Developer program stating that the fourth version of the iPhone Beta SDK. This update includes full support for OpenGL ES and iPhone simulator support for easy code debugging and tweaking.

“OpenGL ES is a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded systems - including consoles, phones, appliances and vehicles. It consists of well-defined subsets of desktop OpenGL, creating a flexible and powerful low-level interface between software and graphics acceleration. OpenGL ES includes profiles for floating-point and fixed-point systems and the EGL specification for portably binding to native windowing systems. OpenGL ES 1.X is for fixed function hardware and offers acceleration, image quality and performance. OpenGL ES 2.X enables full programmable 3D graphics.”

We are getting near the official release of the iPhone/iPod Touch version 2.0 which will bring us access to the official iTunes App Store and more. As of now, no known delays or updates have been published in association with the App Store.
