Facebook has plunked down between $60 and 70 million on mobile app developer Snaptu
, which creates Java-based applications for feature phones
. Snaptu had been hand-picked by Facebook to develop its non-smartphone app, and the acquisition means Snaptu will now be part of the internal team. Snaptu's reach goes beyond Facebook, of course: the company's mobile app also integrates with Twitter, Picasa, LinkedIn, and other services like RSS.
Snaptu's Facebook app works with more than 2,500 handsets. Delivering a powerful, easy-to-use app to the millions of mobile users worldwide who don't own a smartphone is critical if Facebook wishes to make itself as ubiquitous and accessible as possible.
