The popularity of the iPhone doesn’t show signs of subsiding in Korea, with its sales surpassing 700,000 units as of May 22, just six months since its launch here, reports the “Korea Herald” (http://www.koreaherald.com/business/Detail.jsp?newsMLId=20100523000165).

It took 27 days for KT to increase its iPhone subscribers from 500,000 to 600,000, while it took only 25 days to add another 100,000 subscribers. An average of 4,000 users bought the iPhone per day since its rollout in late November, according to KT, the exclusive vendor of the smartphone in Korea, notes the “Herald.”

Meanwhile, the number of iPhone applications made by Korean developers is nearing 6,000, according to Dreamwiz, an iPhone app developer.
