Apple has confirmed the date of the Worldwide Developers Conference, also known as the WWDC, which will now take place in San Francisco on 11 June.Although predominatly an event aimed at developers for the Apple platform, it's also likely to see a significant launch too. In previous years, that has been the next version of Apple's iOS mobile operating system, but Apple has yet to confirm whether iOS 6 will be making an appearance. We suspect it is likely though, especially as this is a software-driven event and because Apple has hinted as much.According to Apple: 'At this year’s five-day conference, developers will learn about the future of iOS and OS X, allowing them to build incredible new apps. WWDC will also feature more than 100 technical sessions presented by Apple engineers as well as the popular Apple Design Awards, a showcase of the most outstanding apps from the past year.'The bigger question is whether Apple is going to go back to its previous schedule and launch a new iPhone too. There have been rumours of a launch at the event, but it just seems a little too soon. The current iPhone 4S has yet to have a serious shelf life, so Apple will be sacrificing sales of that to rush out a new model. Also, with talk of the iPhone 5 being an an all-new design, it's unlikely to be a quick job to develop and test. We would love to be proven wrong though. As for the event itself, well if you fancied it, we have some bad news. It has sold out, taking just two hours to do so. But with tickets at around £1,000 plus hotel costs and travel, you would have to be pretty serious about Apple to be paying out to go.
