OpenFeint is becoming increasingly popular with iPhone app developers thanks to the free and simple social network integration it offers. It currently enjoys around 12 million users across 1000 applications.

The developer behind the platform has just announced the beta testing of its new system OpenFeint X, which will offer a similar service for free microtransaction-supported iPhone games.

OpenFeint X will provide equipped games with a chat system, news feed and an incentive program for users who encourage friends to install games.

“OpenFeint X is the culmination of bringing the best of Xbox Live and Facebook’s App Platform to the iPhone, and extending the multi-billion dollar virtual goods social gaming economy to mobile,” explains OpenFeint's Peter Relan. “OpenFeint X is the platform on which the next big social gaming companies will be created.”

A premium model of OpenFeint X will also be offered to developer wishing to access additional services such as a cloud infrastructure, analytics, and game-specific currencies.
