iPhone 'Hello World' Application

iPhone hacking efforts have been ongoing, but early efforts have provided only a few practical uses (custom ringtones), but one big news item from the community is the first proof-of-concept "Hello World" application has been compiled and launched on the iPhone.

After many, many hours of intense work from "Nightwatch", the first independent "Hello World"* application has been compiled and launched on the iPhone. This was made possible using the "ARM/Mach-O Toolchain", Nightwatch's "special project", that he has been working on so carefully over the past few weeks. Certain parts of the toolchain (such as the assembler) are being refined and tested and these will be released as soon as possible.

No sample code or development tools are yet available, but this may pave the way to future 3rd party iPhone applications. There has been some hope/rumors that Apple may eventually launch their own official SDK, but for now, Apple is sticking to the Web 2.0 development plan and hosting iPhone Tech Talks in major cities to help developers with their iPhone web-applications.
