Apple has just released an iPhone Human Interface Guideline out into the web. This is basically a developer's FAQ for creating web applications optimized to run on their iPhone. Aside from providing for a run-through of the sort of file content that's available on the Apple Mobile, it also offers up guidelines for working with specific design issues on the said phone.

For the iPhone owners, this could be taken as a sign that the company's branching out to make the most of their phone's WiFi connectivity, and its OS. But while web apps optimized for the phone are already an exciting proposition, another clause included in the guide also grabbed our attention:

Note: Currently, developers create web applications for iPhone, not native applications. Therefore, this document focuses solely on the presentation of web applications and other web content on iPhone.

As it says, "currently." While it's too early to tell, are looking at the possibility of Apple releasing developer's kits for running native apps on the iPhone? It's not exactly a far-fetched idea at this point, given that we're already witness to plenty of homebrew applications (NES.app is just one example) for the mobile.
