Wondering when Apple‘s next big shindig was gonna go down? Well, you can mark your calendar for June 7th, because that’s when WWDC 2010, the annual Worldwide Developers Conference, takes place. Of course, the highlight of the event will be the keynote that kicks it off, where we fully expect to see the iPhone HD make its official debut (of course, the iPhone 4 has already been unveiled in an unofficial capacity.) Hey, we are even hearing that there may be bits and pieces revealed about the next major Apple operating system. Exciting times, no?
