The keynote is scheduled at 10:00 a.m. on Monday, June 9, 2008 at San Francisco’s Moscone West. The event runs from June 9 to June 13.

Apple plans to showcase its OS X Leopard and OS X iPhone during over 150 sessions and labs. Mobile developers are to get a taste of the the first iPhone track, allowing them to work with Apple’s staff on applications for the Multi-Touch user interface, animation technology, rich set of APIs, programming interfaces for Core OS, Core Services, Media and Cocoa Touch technologies. And so on.

Still, there’s no word on the 3G iPhone, the gadget that everyone’s been looking for for some time now. Apple is known to be the company that simply loves the idea of “secret”. On the other hand, Apple Store is all out of iPhones, so betting on the 3G iPhone being unveiled at the WWDC (if not sooner) could be a safe bet.

It’s either that or the fruit company is thinking about axing the project altogether. And that’s simply not a valid possibility.
