With the introduction of an Interface Builder and revised APIs, which debuted in Apple’s second beta edition of the iPhone software development kit (SDK) yesterday, developers have a more complete set of tools for putting their code into realistic operation under the included “Aspen” Simulator. Below is a video demonstration of PhotoBoard, an application that started its life under the “Jailbreak” umbrella, and was then ported to the official SDK. The program presents a grid surface upon which photos from the user library can be laid. The grid can then be navigated, and photos rotated and manipulated. It’s essentially akin to Microsoft’s Surface in look and feel. [If you’re on an iPhone, click here to view the video]

The second beta version of the iPhone SDK is now available and includes Interface Builder, a powerful tool that allows you to visually build your interface and makes creating a UI as simple as drag and drop.

We’ve also added new sample code and updated documentation to the rich set of resources available to you in the iPhone Dev Center. Log in to the iPhone Dev Center today and download the new version of the iPhone SDK.

The iPhone is definitely turning into an enterprise heavyweight. Tom Gibbons, head of Microsoft's Specialized Devices and Applications Group (which houses their Mac developers) confirmed to Fortune that Microsoft is looking at bringing native Office apps to the iPhone with the SDK: "To the extent that Mac Office customers have functionality that they need in that environment, we're actually in the process of trying to understand that now." And why wouldn't they? On top of Office apps, TellMe, which Microsoft picked up last year, does voice recognition software, mostly for Windows Mobile, but their general manager said that they're "absolutely going to get a version out there as soon as we can, get TellMe out there on the iPhone." So yes, Microsoft plans to be all over your iPhone.

The Flash drama continues, with more twists and turns than a California highway. It looks as though iPhone may be getting native Flash support after all, if dragged kicking and screaming. Adobe CEO Shantanu Narayen spoke to reporters during a conference call

It seems like only yesterday Apple’s servers were overwhelmed by the unbridled lust of developers, feverishly downloading the newly released iPhone SDK, going offline and back again like cheap Christmas tree lights. Today Apple is reporting that over 100,000 SDK downloads have been made in a span of just four days.
