Apple has indeed failed to deliver a beta version of its new operating system for its tablets - it will be done in the summer, the builder needs a little time to finalize the development of this version.
But that did not stop the Russian hacker Rozetked from filming a demonstration of iOS 7 on an iPad Retina. While it may be a clever fake, it is currently difficult to know by what means he was able to install the OS on a tablet. However, this quick presentation looks pretty true to what iOS 7 could provide to the iPad.
