TUAW received the screen shots above from a tipster (iPhone application developer Drunkenbass) and they most certainly appear to be real. The UI is of course very uniform with other Apple applications and in line with what we would all expect. If the pics are indeed real, then this is likely a very early build of the AppStore interface as we imagine that applications would be split into something like "categories" as opposed to "genres". If the pics are fake then whoever created them probably should have thought of that. Apparently Drunkenbass says that upon initial launch it fires back an "iTunes Connection" error but after several successive launches he finally got it to display some random pages. Would he have had more luck on AT&T? Either way, we’re infinitely more interested with what applications will be making their way to the AppStore as opposed to the UI itself.
