Setup couldn't be easier. Just plug in the WiMax Egg sleeve through the iPhone 4's 30-pin port and you're good to go. To solve the problem that is 4G speeds sucking up battery juice like a hungry octopus, the WiMax Egg sleeve also doubles as a rechargeable battery that'll increase the iPhone 4's battery by another five hours with 4G on. It's like a 4G-enabled Mophie battery pack!
Got your wallet out and ready to hit that "Add to Cart" button? Unless you live in South Korea, you won't be able to buy a WiMax Egg sleeve. But if you do live in SK, then the sleeve will set you back about $130.
