It's not real. The Kid posted on Twitter that he was refused a Dev account and so faked the Beta. He wrote the Dictionary and iStore apps himself along with the Spotlight tweaks.
wow looks really legit, the person using it doesnt sound like a dev but hey you never know, now if the video is taken down in 24 hours that means its the real thing
Doubt it's real, but I would love everything he has installed on my iPod and iPhone. Release now! I really doubt that's real, but hope it is kind of. If it somehow was, I would be slightly disappointed. I expect more.
