When Apple launched their iPhone 4, it seemed to have so many breakthroughs (well at least Apple made us think it had). But fast forward a year, and now the iPhone 4 seemed to lack so many things compared to those newer Android phones. I’m not going to talk about dual-cores, but the iPhone 4 only had a 3G radio chip, whereas most phones these days are said to be 4G as they support HSPA+. Now, what if your iPhone 4 can easily get WiMAX support through a case?

That’s what the Korean did. Korean Telecom’s new Egg sleeve gave WiMAX to the iPhone 4, but also incorporates an extra battery to allow five hours of 4G surfing. What more can you ask for? Of course, doing so will add bulkiness to your slimly beautiful iPhone 4, which actually adds up 68g and 8mm to your magical phone.

The thing ain’t really that pricey at ₩129,800 ($120) but you’ll have a hard time getting them outside of Korea. Notice that sinister smile in the picture above? That’s why!
