Apple said today it has sold 3 million iPads in the 80 days since the tablet first became available.
There are also now more than 11,000 programs, or "apps" available for the iPad, the company said.
The tablet comes in a Wi-Fi only version, as well as another that also has 3G wireless service for Internet access via AT&T.
The Federal Bureau of Investigation recently started a probe into a security breach that exposed personal information of AT&T iPad customers, including those of several high-ranking government officials.
The breach, first reported by the website Gawker, occurred when a group calling itself Goatse Security hacked into AT&T's iPad subscriber data, obtaining a list of e-mail addresses that also included celebrities, chief executives and politicians.
