The annual developers conference Worldwide Developers Conference 2009 (WWDC) is to be held from June 8 to 12 this year.

Apple announced it just last week on Thursday, where the conference would be held at Moscone West convention center downtown San Francisco.

Tickets to the five day event are now on sale, where special sale offer tickets are available till April 24th.

I reckon the new-gen iPhone will be unveiled then, plus not to forget the Mac OS X 10.6 Snow Leopard operating system.
