Let's face it, the iPhone would be so much more awesome if it was partly powered by the Flux Capacitor from Back to the Future. Here's a great video created by Additifs that gives us a glimpse at what such an iPhone might look like, and the features it might include, such as iTime. It's called iPhone 6 Revolution - The Flux Capacitor, and I wish it existed because I want one! Thanks to Cult of Mac for the heads up.
