A company representative was not immediately available Monday to say what portion of the sales were abroad.
The company had previously said it sold 1 million iPads in the United States just 28 days after its launch. As a result of the strong demand at home, Apple had pushed back the start date of its international sales.
The iPad can be used to send e-mails, draw pictures and play games. It can also be used as an electronic reader. The basic model costs $499 in the United States, not including extras.
