The Apple Worldwide Developers Conference (WWDC) has just been announced, and this year the event will take place at Moscone West in San Francisco, from June 6th to June 10th.

Developes are invited to “a preview of the future of iOS and Mac OS X“. There has also been some speculations of new details about iOS 5 or at least a new version of iOS 4.

The previous four years, Apple has used the summer event to launch a new version of yje iPhone. This time, however, there is still no signs indicating that Apple will launch an iPhone 5 at the WWDC. Actually, the fact that the invitation is very focused on operating systems, indicates that this will probably not happen.

The Apple Worldwide Developers Conference (WWDC) showcases the latest innovations and the newest technologies in iOS and Mac OS X. Over 1,000 Apple engineers guide you through five exciting days of in-depth technical sessions and hands-on labs that demonstrate how to harness the incredible power of the world’s most advanced operating systems into your apps.
