Apple PR:

Apple today announced it has sold three million of its incredible new iPad, since its launch on Friday, March 16.

Phil Schiller calls it "a blockbuster" and "the strongest iPad launch yet".

AT&T released a statement too:

On Friday, March 16, AT&T set a new single-day record for its iPad sales and activations, demonstrating robust demand for the new iPad on the nation's largest 4G network, covering nearly 250 million people.

Not bad for a supposedly "minor update".
