Apple announced that it will hold its annual Worldwide Developers Conference (WWDC) from June 7 through June 11 at San Francisco’s Moscone West. The five-day conference reportedly will include iPad development sessions and hands-on working labs for iPhone OS 4.

WWDC 2010 is focused on providing advanced content for developers across five technology tracks: Application Frameworks; Internet & Web; Graphics & Media; Developer Tools; and Core OS.

Aside from the developer aspect of the conference, the rumor mill is already cranking up that this will be the event where Apple introduces the next-generation iPhone to complement the new version of its mobile OS, iPhone OS 4.0. The current 3GS iPhone was officially unveiled at last year’s WWDC.
