KT intros sleeve with WiMAX, auxiliary battery

Korean Telecom introduced a new sled case for the iPhone 4, the KWF-B2500 from its Portable Mobile WiMax Egg series. It provides WiMAX-based 4G access and has a 1,500mAh battery to extend battery life by about four hours. It adds 0.31in to the thickness of the iPhone 4 and weighs 2.4 ounces.

The carrier also showed off the KM-MR100 Wireless WiMax portable hotspot. It is 60 percent smaller than the previous model and is said to last four hours on a full charge.

Each device is now available in Korea for 128,000 Won (about $118) each. [via Akihabara]
