Ask any moderately serious iPhone 3G user about the device's biggest weaknesses and most will say battery life and the unit's susceptibility to scratches. Mophie's Juice Pack Air iPhone battery pack attempts to address both of these issues simultaneously, with a companion product to the very popular Juice Pack for iPhone 3G. I take my power-hungry iPhone 3G for a spin with the shiny new Juice Pack Air to see if for $79 you can have it all.
