CTech already published a specs sheet (http://www.gsmarena.com/alleged_iphone_5s_specs_show_only_minor_changes-news-6751.php) for the iPhone 5S, but it seems the site has also gotten hold of a 15 second video showing the cheaper iPhone 5C (recognized by its colored plastic sides) that shows the device being unlocked, a quick peek at the app launcher and then the browser.

Not that iOS 7 is in any way new
