The Beta 5 version of the iPhone SDK is now out. Unlike the previous release, this one doesn’t bring much new to the table. However, tweaks to the developers tools and some bug fixes should be more than enough for any iPhone/iPod Touch developer out there to update.
This fifth beta release of the iPhone SDK includes a complete set of tools, compilers, frameworks, and documentation for creating iPhone OS applications. These tools include the Xcode IDE, and the Instruments analysis tool, among many others. With this software you can develop applications that run on iPhone and iPod touch using the included iPhone Simulator.
