iPhones, iPads and iPod touches could become "black, white and flat all over" with the next iteration of Apple's mobile operating system, iOS 7.

That’s according to 9To5Mac, which, following its report in April, has once again spoken to its anonymous sources to find out further details about Apple's upcoming iOS 7, which is expected to be unveiled at WWDC on 10 June.

The sources have said that Apple's design guru Jony Ive is pushing for a complete iOS 7 overhaul with a flatter redesign, ditching skeuomorphic design elements in favour of a more minimalist look.

iOS 7 will be "black, white and flat all over," according to the sources, who say that Ive has voiced his opinions about the use heavy textures in iOS during software design meetings at Apple. He believes that "software designs filled with physical metaphors do not stand the test of time," a person familiar with the meetings allegedly told 9To5Mac.

 

Ive is also said to have highlighted the inconsistent designs of Apple's iOS apps, which could cause confusion for some users.

9To5Mac's report claims that the Lock screen in iOS 7 may have some significant design changes. 

"With iOS 7, Apple will drop the shiny, transparent time bar on the top of the Lock screen in exchange for a shine-free, black interface," says the report. "Additionally, the square-grid for entering a pin code has been replaced with round, black buttons with white text and white borders."

Notifications on the Lock screen could also get more gesture-based features, the sources say.

While these design changes will make the Lock screen look different, the functionality is thought to be remaining largely the same.

Another change expected to arrive with iOS 7 is the introduction of quick access panels that will display information such as localised news feeds, as well as an easy way to turn on and off WiFi, Airplane mode and Bluetooth – a feature wished for by many iPhone, iPad and iPod users.

As for the Home Screen, the sources say that it will remain mostly the same as it is in iOS 6, with possible tweaks coming in the form of a panorama-like wallpaper that can span across several screens, as well as shine-less icons.

Overall, if 9To5Mac's sources prove to be legitimate, expect to see a texture-, shine- and animation-less iOS 7, from the Lock screen right through to Apple's apps, including Calendar, Mail, Maps, Notes, Passbook, Weather, Game Center and more.

Finally, new features in iOS 7, in addition to all of those design changes, could include Flickr and Vimeo integration and Maps and Siri improvements.

It has been rumoured that Jony Ive has been pushing for a flatter design for iOS 7 since as far back as last year. In October, an executive shakeup at Apple saw then head of iOS software Scott Forstall leave the company, which meant Ive took on more responsibilities as the leader of human interface at Apple. This means that, as well as hardware design leadership, Ive now has more involvement with the design of iOS and other Apple platforms.

Ive's promotion sparked speculation that Apple may be considering dropping its skeuomorphic design elements in favour of a cleaner, more minimalist design.
