Tickets to Apple's WWDC 2012 sell out in two hours

Apple announced the dates for WWDC and began selling tickets at 8:30 a.m. Eastern on Wednesday. But by 10:30 a.m., the official WWDC website was no longer accepting registrations.

"Sorry, tickets are sold out," the site reads. "We’ll be posting videos of all our sessions shortly after the conference, so everyone can take advantage of great WWDC content for free."

The two-hour sellout is the fastest ever for Apple's annual developers conference. Last year, WWDC sold out in a record 10 hours, while in 2010 it took Apple 8 days to sell all of the tickets.

The event will kick off on June 11 at San Francisco's Moscone West center, which can accommodate roughly 5,000 attendees. Apple has promised to show off the future of iOS and OS X at this year's conference.

Last year, Apple used WWDC to unveil iOS 5 and also to highlight features from OS X 10.7 Lion. It's presumed that this year will be a similarly software-focused event with the unveiling of iOS 6 and new details on OS X 10.8 Mountain Lion, both of which are expected to become publicly available later this year.

Though the conference is officially sold out, Apple's website still offers the opportunity for students who build applications to apply for a WWDC 2012 Student Scholarship.
