Samsung announced that they sold over 5 million Galaxy Note II phones. In the beginning of November they announced 3 million units sold - so it means they sold 2 million in less than a month. The Note II has a 5.5" HD Super AMOLED display (1280x720, non-Pentile), a quad-core 1.6Ghz processor and a large 3,100mAh battery. It's only 9.4mm thick.
The Note 2 started shipping in September 2012. It's available for AT&T ($250), and also unlocked in the US for $775 (international version).
