The buzz earlier this year was that iOS 7, the next major release of Apple's mobile operating system, would debut alongside the new iPhone 5S. That hasn't happened, obviously, but Apple is expected to unveil iOS 7 at WWDC.
The changes may be visually dramatic, if largely cosmetic. Jony Ive, Apple's chief of industrial design, will reportedly replace iOS's traditional 3-D appearance with a flatter look (think Windows Phone 8). In addition, skeuomorphic elements -- meaning digital features that resemble their real-world counterparts -- of the iOS interface may be history as well. If true, the gaming table on the Game Center screen (seen here) is a prime candidate for Ives' iOS makeover.
Other iOS 7 upgrades may include improved Maps and Siri integration with cars, and better hooks into social networks, including Flickr and Vimeo, said 9to5Mac.
