"The fourth beta version of the iPhone SDK includes Xcode IDE, iPhone simulator with Open GL ES support, Interface Builder, Instruments, frameworks and samples, compilers, and Shark analysis tool."Developers are continuing to work on iPhone/Touch apps and games to ready for the June launch of the iTunes App Store.
