AT&T said during their earnings call that the new iPhone 3G sold twice as many units in the first 12 days compared to the first generation iPhone a year ago.

AT&T had a quite good quarter that does not even include the iPhone 3G yet. AT&T’s profit rose by 30% to $3.77 billion.

The carrier could sign an additional of 1.2m subscribers during last quarter.
We can expect a pretty good next quarter that will include the iPhone 3G.
