All passes for Apple's Worldwide Developers Conference, which runs June 7 - 11 at San Francisco's Moscone Center, were sold as of yesterday. The annual conference caters to Mac OS X and iPhone OS developers. Apple has been less than subtle about demonstrating that the mobile OS has become the favored child in the family, though.
It is expected that iPhone OS 4 will headline the event, with tracks on multitasking of iPhone and iPad apps, working with the iAd in-app advertising solution, and taking advantage of the 100+ new features in the mobile operating system. Sessions on coding for Mac OS X, HTML5 local storage, and network applications are also expected to be popular among developers. As in past years, many Apple watchers expect that the next generation iPhone will be introduced at the show.
By announcing the dates for WWDC 2010 a little more than a month before the show, Apple had already received criticism from developers who complained that they would not have time to make flight and hotel reservations. What's up for next year? "Hi ... we're having WWDC next week. Can you come?"
