Apple has released the 3.0 version of iPhone SDK for iPhone developers. The 2.0 Beta version of the iPhone SDK was pretty hit among the developers and many third party application companies announced games and software exclusively for the iPhone, courtesy the iPhone SDK. The 3.0 version has most of the bugs taken care of and also supports the latest iPhone OS that runs on the iPhone. This time Apple plans to reduce the bug reporting from the developers. Apart from all these functions the SDK 3.0 has Interface Builder, Xcode IDE, Instruments, iPhone simulator, frameworks & samples, compilers, and Shark analysis tool.
