This thing, called the "Wimax sleeve for iPhone 4", can make your iPhone 4 works on WIMAX network operated around your area. The KWF-B2500 launched by KT (Korea Telecom) as a part of its new portable Mobile Wimax Egg Series. This is a wimax sleeve made compatible with iPhone 4 only.
The iPhone 4 Wimax sleeve comes with 1500mAh battery that can make your iPhone4 not only can work on 4G WIMAX service but also promises longer battery life without re-charging your iPhone battery.
No word mentioned that this Wimax 4G sleeve for iPhone 4 will marketed out of Korea, however this make me remember to ZTE Peel a few months ago, that can make iPhone and iPod to works with CDMA radio frequency. Its very interesting to hear some time, the same company also make the same iPhone sleeve for LTE 4G network. Akihabaranews()
