My, how far we've come. Believe it or not, Mophie's Juice Pack pack is in its seventh generation of product development, with the latest 'Air' supporting Apple's polarizing iPhone 4. For those unaware, these cases nearly double the battery life of the phone they're wrapped around, and better still, it acts as protection against drops and dropped calls. Fancy that! This little guy is said to provide up to six extra hours of 3G talk time, 36 hours of bonus audio playback or nine hours of video playback. It's shipping now, just like we said, to those willing to part ways with $79.95, and it's available in any color you want, so long as it's black.
