has sold over 4 million units of its popular and overhyped iPhone since its introduction back in June 2007.
During his keynote at Macworld, Apple's CEO, Steve Jobs, said that the company was pleased with the results and that the average daily sales were in excess of 20,000 iPhones.
In spite of this, it won't be easy to reach the optimistic sales goals announced last summer. With five months to go Apple is still 6 million units short of its ultimate goal of selling 10 million units in its first year on the market.
The iPhone has faced some setbacks: unimpressive sales in Europe, recent troubles with the planned launch in China and Apple's reluctance to aggressively enter certain European markets.
