iPhone 3G Juice Pack received universal praise, and while the additional baggage bothered some, most users just appreciated being able to utilize 3G for more than 47 seconds without needing an AC outlet. Not one to rest on its laurels, the company has today introduced the new and improved version: Juice Pack Air. Contrary to popular belief, this actually isn't intended for Apple's MacBook Air (now there's an idea to capitalize on, mophie), but instead, it's the planet's thinnest external iPhone 3G battery / case. The device houses a rechargeable 1,200mAh battery that "virtually doubles the amount of time you have to rock, talk, surf, and send messages." Eager consumers can pre-order theirs now in black, purple or white, while patient souls can mellow out until they hit mophie's website and Apple stores everywhere this Spring. Full release is after the jump.
