In collaboration with Snaptu, a company that specializes in developing stripped-down apps for use on so-called "dumb phones," Facebook has launched an app which will work on about 2500 devices from a range of manufacturers including Nokia, Sony Ericsson, and LG. It aims to provide a similar experience to that of its fancier smartphone counterpart.
It appears that the focus (at least initially) is to expand mobile usage of the site into developing markets. Facebook has struck deals with several carriers across Asia, Europe, and the Dominican Republic to offer use of the app for 90 days without any data charges.
