The latest version of the iPhone went on sale in France, Germany, Japan, the UK, and the US in late June. The iPhone is Apple's main growth driver and is soon expected to become its largest source of revenue.
At a press conference last week, Apple CEO Steve Jobs noted the iPhone will not debut in South Korea just yet. Apple's top rivals, Samsung Electronics and LG Electronics, are centered in the country and the iPhone must be approved by the South Korean government prior to distribution.
The iPhone 4 will be available for purchase in 88 countries by September—the company's fastest-ever global product launch.
