Among wireless devices, smartphones account for 60% of the traffic to premium mobile sites, according to a new study by mobile ad network Quattro Wireless. BlackBerry devices made up 48% of all smartphone traffic on the Quattro network, followed by the iPhone, with 18%.

The company said the findings show that smartphones are no longer the province of only business travelers or other heavy-duty mobile users. Demand for devices with large screens and keyboards now cuts across most demographics, incomes and geographies, said Quattro.

Ads on the more than 100 premium off-deck sites in the company's network get an average of three page views post-click, with movie-related landing pages proving the most popular. The results were based on data gathered by Quattro between January and April 2008.
