Previewed at WWDC, launching in the fall.
WWDC Sells Out for the First Time in History
Apple confirmed to Macworld that the 2008 Worldwide Developer Conference (WWDC) has sold out for the first time.
"Response to this year's WWDC has been off the charts and we are delighted with the show of enthusiasm and support from the developer community for the new iPhone SDK," Apple spokesman Bill Evans told Macworld. "The conference is now sold out. For those unable to attend WWDC, session videos will be available to purchase on iTunes shortly after the conference."
Apple declined to provide an exact tally for the record-breaking attendance. Certainly, opening the conference up to iPhone developers has increased interest in Apple's developer conference.
