Q4 2006 sales were up 14% over the previous year, and mobile phone sales to consumers totaled $8.8 billion after rebates and promotions.

"US handset sales remained strong throughout 2006," said Ross Rubin of the NPD Group. "A continual flow of new devices with data-capable features, combined with carrier promotions and rebates, have served to broaden the market of consumers who purchase new phones and wireless plans."

About a third of mobile phones sold in Q4 2006 were music-enabled, up from 18% in Q2.

About half of all phones sold in Q4 supported Bluetooth, and two-thirds of all mobile devices were camera phones.

Cingular/AT&T had 27% of all subscribers and 27% of all new phone sales in 2006. Verizon had 27% of all subscribers, but only 23% of new phone sales.
