If you want to know how important iPhone application development is to Apple, you should take a look at the schedule of the sessions at the much-awaited Worldwide Developers Conference or WWDC. The iPhone-related sessions occupies the one-third of the whole session that will be hosted by Apple Inc. during the WWDC which would last up to five days. The event will be at San Francisco and will start on June 9.

The developers already had an early glimpse of the iPhone SDK or Software Development Kit. As of now, the SDK already have six beta versions. The SDK allows the developers to create native iPhone applications. With the help of the various sessions that will be conducted during the WWDC, developers will gain more knowledge and information as well as access to the engineers of Apple Inc.

When iPhone had its first launch, the only way for the developers to write a software is through the help of iPhone’s web browser – Safari. The software can only be written as a web application. Fortunately, after four months since iPhone was launched, Apple announced that they would have an SDK so that developers can create native iPhone applications.

However, Apple made it clear that the WWDC is not just about the iPhone. The focus of the event is also about the ways on how to develop the Mac.
