Apple on Monday said iPhone 4 sales topped 1.7 million units for the first three days the device was available to customers.

Apple CEO Steve Jobs said the iPhone 4, which hit retail outlets Thursday, was "the most successful product launch in Apple's history" and apologized to customers who were turned away because there weren't enough iPhone 4s to go around.

In 2008 and 2009, respectively, Apple sold 1 million each of the iPhone 3G and the iPhone 3GS in their initial weekend of sales.

The iPhone 4 launch hasn't been without its difficulties for Apple. As soon as the device became available, users began complaining about problems with the antenna.
