On Wednesday morning, Apple revealed the launch date of the widely-expected iPhone SDK. The Cupertino company has sent invitations to the press for an event in which it will discuss the iPhone software roadmap and “some exciting new enterprise features”.

"Please join us to learn about the iPhone software roadmap, including the iPhone SDK and some exciting new enterprise features," reads the invitation sent to reporters.

Announced in October 2007 by Steve Jobs himself, the iPhone SDK, which will open the phone’s platform to the third-party developers, was scheduled to be released this month.

“We are excited about creating a vibrant third party developer community around the iPhone and enabling hundreds of new applications for our users. With our revolutionary multi-touch interface, powerful hardware and advanced software architecture, we believe we have created the best mobile platform ever for developers”, wrote Jobs in October in an announcement posted on Apple’s web site.

With the iPhone SDK, developers can create Web 2.0 applications which look and behave just like the applications built into iPhone, and which can seamlessly access iPhone’s services, including making a phone call, sending an email and displaying a location in Google Maps. The iPhone does not have a chat application, for example. The iPhone SDK will allow developers to create applications for iPod Touch.

The release of iPhone SDK may also boost the sales of Apple’s cell phone and help the company to reach the 10 million units sold mark.

So far, Apple didn’t released any details about the iPhone SDK, besides what Jobs wroted in his October’s message: “We are working on an advanced system which will offer developers broad access to natively program the iPhone’s amazing software platform while at the same time protecting users from malicious programs”. Earlier today, Apple released the 1.1.4 firmware for iPhone, which has fixed several “undisclosed” bugs.
