The first hint of what Apple will be offering for mobile users should be revealed at the upcoming WWDC event.The tech giant has confirmed that this year's WWDC conference will take place between 10 and 14 June. No details on just what will be be announced, but if previous form is anything to go by, Apple should be showcasing its latest software. In the case of mobile, that will be iOS 7. There could be hardware, but mobile launches are unlikely.Indeed, Apple's own site confirms some developments on the mobile front: 'Get an in-depth look at what’s next in iOS and OS X, and learn how to take your apps to the next level. With over 100 sessions, extensive hands–on labs, and engaging events, you’ll connect with Apple engineers and fellow developers for an incredible week of inspiration.'iOS 7 is slightly more exciting this year, as it should be the first time that it has had a graphical makeover since the operating system launched. As we mentioned previously, Apple's VP of industrial design, Jonathan Ive, has reworked the interface. The new version is being described as a modern 'flat' design - but we'll probably have to wait until the launch to see what that means.It was also said to be running behind, but judging by Apple's words, it looks like we'll have at least something to show off in June, with some features likely to follow further down the line. Presumably when the new hardware appears in the autumn.When anything is revealed, we'll certainly have the lowdown on it.
