Apple's new tablet PC goes on sale in Korea on Friday, one month after the U.S. tech giant launched it in the U.S. and Japan on March 16. Apple will also start selling the new iPad in another 19 countries including Panama and Uruguay, it said on Tuesday.

The hot new gadget offers greatly improved resolution with its powerful display, which packs four times as many pixels as the iPad 2. It also boasts a faster A5X processor, a quad-core graphics chip and an upgraded five-megapixel iSight camera, not to mention over 10 hours of battery life.

In Korea, Apple will sell a Wi-Fi only version, as well as a 3G and Wi-Fi combined model. A 4G version is available in some foreign markets, but it will be replaced by a 3G version here because of different 4G frequency bands.

SK Telecom and KT will start receiving subscriptions at their respective websites and outlets across the country this week.
