WWDC 2012 sold out in under two hours last year. It was insane. A lot of people on the West Coast didn’t even get a chance to buy a ticket because Apple announced tickets were available at 5am.
Everyone who’s really wanting to go to WWDC this year is probably looking for the best method to alert them on tickets, so Oisin Prendiville has created a service that will call you as soon as tickets are available.
