In an attempt to revive its app store platform App World, Research In Motion (RIM) has acquired Cellmania, the app store infrastructure developer which developers, manages as well as distributes mobile application storefronts for handset operators.

Cellmania, which lists Sprint as one of the content providers using its infrastructure, essentially sells a product called ‘mFinder’ – a product that pertains to content delivery and app store ecosystem infrastructure.

The acquisition of Cellmania – the company that had raised over $21 million in venture capital funding from BroadVision, Pino Venture Partners, ZAP Ventures, and Office Depot – will help RIM improve its app store platform, which though has been existence for the BlackBerry handsets, but has failed to handsets actually take off.

Talking about the acquisition by RIM, Cellmania said on its website that it “is pleased to announce that it is now part of Research in Motion.” The company further added that it “has joined RIM’s global organization and will continue to bring its expertise in Application Storefront development to the Blackberry platform.”

The takeover of Cellmania is not RIM’s first indication to show that the company intends resuscitating its App World apps platform. A week back, the Wall Street Journal reported that RIM was in search of a mobile ad network – similar to Google’s AdMob and Apple’s Quattro Wireless – which would help it easily monetize its apps.
