Want 4G On Your iPhone 4? No Worries The WiMAX Sleeve Has You Covered
There has been a lot of weird stuff coming out of Korea lately but this might be the useful one yet, Korean Telecom has developed a new egg sleeve which allows your iPhone 4 to use WiMAX like some of it’s Android buddies (Nexus S 4G to be precise). The Sleeve also has an inbuilt battery which gives you over 5 hours of 4G surfing. The WiMAX sleeve weighs in around 2.4 ounces (68g) and would make your iPhone 4 a third of an inch thicker (8mm). The ₩129,800 ($120) sleeve is currently South Korea only with no plan for an international release.
