iPhone SDK reaches fourth beta

Apple has started distribution of the fourth beta of its SDK for the iPhone and iPod Touch, reports TUAW.

The latest version includes an upgraded emulator that supports OpenGL ES, allowing game developers to test their games straight from the desktop. Prior to this, the only way to test applications that used OpenGL ES would have been to deploy the app to a device – a feature restricted to iPhone Developer Program members, membership of which is currently limited to people in the US.

The SDK, available at the Apple Developer Connection website, weighs in at 1.15Gb and includes the Xcode IDE, iPhone simulator, Interface Builder, Instruments, frameworks, samples and the Shark analysis tool.
