^^^ To answer your question from the other thread if this is a real iPhone concept...the answer is a resounding NO. Not only is the concept itself a bit silly from a practicality and mechanical standpoint (amongst other things), this kind of release wouldn't be done over YouTube, you'll see the new iPhone coming from a mile away when even the tiniest of little specs of information come out (mostly internal stuff), some leaks will hit, maybe even a vague picture or design drawing...and that will be a good bit before the official announcement keynote, where legitimate videos and pictures will come from.
To help yourself in the future, you won't find pre-production videos of any new iPhone on YouTube first...and our forums will be on FIRE with any legitimate leaks, so just look for them here first.
