Samsung recently announced that they have sold 2 million units of the Samsung Galaxy S II handset in South Korea, which took only 73 days since its release, which is almost half the time it took for the Samsung Galaxy S to reach that figure. To celebrate that milestone, Samsung will be releasing uniquely designed battery covers for the device and they will sold in limited quantities. We’re not sure if those covers are available only in South Korea or if they will be made available worldwide, but either way they do look pretty good.
