Busted! Facebook Fudges iPhone User Numbers (AAPL)

Facebook was called out yesterday for falsely claiming that there are 100 million monthly active users of its Facebook for iPhone app. Apparently, 100 million devices using Apple's AAPL iOS software (iPod touch, iPhone, and iPad) have been sold as of June, 2010. Clearly, something was askew. Facebook was previously showing just over 100 million users of its Facebook for iPhone app, nearly 60 million BlackBerry users, and a bit more than 12 million using the Android client. Facebook put out a statement revising its number to 44 million monthly active users. "There are currently 44 million monthly active users of the Facebook for iPhone app. We recently changed the definition of mobile active users to exclude those who have only liked or commented on stream stories. Instead we are counting "active" users as people who have taken explicit actions within an application. This practice is more aligned with how we count overall active users for the site." Shares of Apple are down 0.6% this afternoon, to $241.45.
