Apple has announced that it will be commencing its annual Worldwide Developers Conference (WWDC) this year with a keynote address on Monday, June 8, at 10:00 a.m. The keynote will be delivered by a team of Apple executives led not by CEO Steve Jobs, but by Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. 

According to the press release, Apple will use its annual conference aimed at development to offer in-depth sessions on iPhone OS 3.0, and Snow Leopard, the upcoming version of the Mac OS. Those aimed at the latter will also feature technical presentations showcasing hundreds of refinements to the operating system, while going deep into its 64-bit architecture, QuickTime X, multicore and GPU processor support, as well as new accessibility technologies.

On the iPhone side, OS 3.0 sessions will talk about advanced concepts to help developers get the most out of the iPhone OS 3.0 SDK and over 1,000 new APIs available for iPhone OS 3.0, all on an introductory level. Apple claims WWDC offers attendees the unique opportunity to work side-by-side with Apple engineers to get expert advice on their work.

“Last June, we gave developers an early look at the powerful new technologies that form the underpinnings of Mac OS X Snow Leopard,” Bertrand Serlet, Apple’s senior vice president of Software Engineering, said. “At WWDC, we will be giving our developers a final Developer Preview release so they can see the incredible progress we’ve made on Snow Leopard and work with us as we move toward its final release.” 

Apple also posts other activities scheduled for this year's conference, including:

– more than 100 technical sessions presented by Apple engineers on a wide range of technology-specific topics for developing, deploying and integrating iPhone OS 3.0 and Mac OS X technologies;
– over 1,000 Apple engineers presenting the latest in Apple technologies and providing one-to-one direction in hands-on labs; and
– the opportunity to connect with thousands of fellow iPhone and Mac developers from around the world.
