iPhone SDK Beta 4 Released

A few days ago, Apple quietly release the fourth installment of its iPhone Software Development Kit (SDK), and it is available on the Apple Developer Center site.

The most publicized and prominent change in the newest SDK version are certain changes to the iPhone simulator. Previously, a developer would be unable to render 3D graphics in the iPhone simulator, and would be forced to test out those changes on the iPhone or iPod touch. The Simulator now supports OpenGL ES, allowing the previously mentioned rendering to happen within the iPhone simulator, right on your computer. Another prominent addition to the SDK is code signing, so though invalidated code will work in the iPhone Simulator, it would be worthless on the iPhone.

Other less significant changes in the SDK include a slimmed down program, while still maintaining the full capabilities of the last version. Xcode 3.1 has been included, along with UIFont, UIApplication, Audio ToolBox, and more NSXMLParser support. With 200,000 subscribed developers and counting, you can be sure to expect a good handful of great new apps available when the App Store opens its doors in June
