Apple's annual Worldwide Developers Conference (WWDC) 2009 is sold out. The company posted a note on its Web site Tuesday afternoon with the news.

WWDC is Apple's conference where developers gather in San Francisco to hear the latest news on development tools.

Typically developers get the latest updates from Apple in both software and best practices when writing software.

Of course, iPhone OS 3.0 will be a hot topic at this year's conference, as developers figure out what tools they have available to make the next round of cool apps.

A list of conference sessions is available from Apple's Web site.

WWDC takes place in San Francisco from June 8-12, 2009. Videos will be available for purchase shortly after the conference ends, so if you can't go, you can still get the news and training.
