Apple released the second beta version of its software development kit for the iPhone Thursday. The new version contains one significant upgrade: the Interface Builder, a visual editor that lets developers drag and drop icons to easily create the user interface in their applications.

Some developers had been holding off working on iPhone apps until the interface tool arrived.

While several big-name companies have signed on to develop applications for the iPhone, many independent developers have expressed dismay at the level of access the SDK permits.

Microsoft: iPhone Developer

The latest major company to express interest in iPhone development is Microsoft, which, Fortune reported earlier that week, has been poring by the SDK. “It’s really crucial for us to understand what we can bring to the iPhone,” said Tom Gibbons, vice president of Microsoft’s specialized devices and applications group. “To the extent that Mac Office customers have the functionality they need in that environment — we’re actually

in the process of trying to understand that now.”

Microsoft is one of the largest developers for the Mac outside of Apple and it knows about mobile applications, so it would be well positioned to deliver iPhone apps. “We do have experience with that environment, and that gives us the confidence to be able to do something,” Gibbons said. “The key question is, what is the value that we need to bring? We’re still getting comfortable with the SDK, right? It’s just come out.”

Besides Microsoft Office for Mac, Microsoft may well bring its TellMe voice-recognition application — acquired a year ago — to the iPhone. whether Apple allows applications to do voice recording and location identification, “We’re absolutely going to get a version [of TellMe] out there as soon as we can,” said Gibbons.
