The iPhone 4's namesake can spell a lot of confusion for the novice gadgeteer. The inclusion of the 4 may cause the less knowledgeable to assume it has 4G network capabilities, like a number of it's 4G Android competitors. Korean Telecom (KT) eliminated any confusion, and subsequent disappointment, for their customers today with the release of it's new WiMax capable sleeve the "Egg."

KT's Egg Sleeve allows the iPhone 4 to utilize their WiMax network and includes a 1500mA expansion battery that offers an additional five hours of WiMax surfing goodness. The case adds 68g to iPhones weight and just over 17mm to its thickness. It's definitely not the smallest case/sleeve, but the prospect of a Mophie Juice-like case that adds WiMax functionality is enticing. Unfortunately, the case is only available in South Korea for 128,000 Won (about $120).

However, United States dwelling folk can still purchase mobile 4G wifi hotspots from their respective provider. It's not quite as elegant of a solution, but I can't imagine it taking too long before we see a similar 4G case here in the States. The only hold up is the lack of 4G coverage in the U.S. KT blankets 85% of South Korea with WiMax coverage, a testament to their dedication to wireless networks and the smaller footprint of the country itself.
