LIVE FROM BLACKBERRY DEVCON EUROPE: RIM said that, on average, more than 6 million downloads are made from its BlackBerry App World store each day, while also highlighting the benefits to developers of the latest version of the store – App World 3.1.

Alec Saunders, VP of developer relations and ecosystems development for the company, said in a presentation that this marks a 30 percent increase over the volumes seen three months ago. Driving growth is “the proliferation of BlackBerry 6 and now BlackBerry 7 devices,” he said.

The store now has a catalogue of more than 60,000 apps. It is available in 164 markets worldwide, “and growing,” with 26 different currencies supported.

Noting the recent introduction of the latest version of App World, Saunders noted the importance of carrier billing support, stating that this is “a tremendous initiative for developers, and it is present directly in App World 3.1.” It is currently supported by 40 operator partners worldwide, and is now the default payment method where available.

According to the executive, carrier billing now represents 34 percent of purchases from App World. RIM’s operator partners have indicated that customers who use this payment method have 70 percent more paid apps than other BlackBerry users – and install twice as many apps in total.

Other new features added in App World 3.1 are support for languages including Chinese, Dutch, Indonesian and Korean; and content rating and filtering.
