Social games publisher SGN continues to be bullish about iPhone, revealing that it's now racked up more than 13 million downloads of its games on the App Store.

"Apple has confirmed that unit sales are more than 30 million for the iPhone and iPod touch. Given these statistics, SGN games are already on one in three devices," says CEO Shervin Pishevar.

He also thinks that iPhone is posing serious questions to traditional console games companies - both manufacturers and publishers.

"Business models have shifted underneath traditional console companies," he says. "It is now easier for small nimble companies to come in and innovate and shift the gaming space. SGN is able to go from ideas to execution to game launch within 30 - 45 days, which is unheard of."
SGN is also putting iPhone 3.0 features into its games, such as in-app payments in F.A.S.T. and Vampires vs Werewolves. It's hoping for similar success to Facebook, where Pishevar says it's making an average of $50 in micro-transactions per paying user every month.

"We believe the iPhone is the future of social mobile gaming," he says. For the full interview, head over to PocketGamer.biz.
