Reader @Late2thePartyDV sent us this video from a Facebook page, asking whether or not this is the official iPhone 5 keynote video (the official launch is set to go live at 10 a.m. today, by the way). Or is it a brilliant mock up?

Below shows a screen grab from the video noting that the next generation phone is 9mm taller and 22% thinner. (Again, this is all speculation until Apple makes it official.)
