Today from Apple:

Apple® today announced that it has sold over 1.7 million of its iPhone® 4 through Saturday, June 26, just three days after its launch on June 24. The new iPhone 4 features FaceTime®, which makes video calling as easy as one tap, and Apple’s new Retina display, the highest resolution display ever built into a phone, resulting in stunning text, images and video.

“This is the most successful product launch in Apple’s history,” said Steve Jobs, Apple’s CEO. “Even so, we apologize to those customers who were turned away because we did not have enough supply.”
