There are apparently some working iPhone 6 clones from China, according to released pictures by NowehereElse.fr. The devices in the pictures released sport the rumored schematics and specifications of what everyone has been talking about in the last few weeks. The only differences are that the devices do not run on iOS and use internals you can buy from stores.
It is unclear as to what operating system the knockoff devices are running on. However, it is likely that it is an Android operating system with an iOS 7 custom launcher. The Google Play Store has a list full of iOS 7 app clones and Home screens. The official iPhone 6 is expected to launch sometime in September with at least the 4.7-inch display and the other 5.5-inch display is expected to be touched upon.
