Facebook is unveiling what's expected to be a big change in the way millions of mobile users access the site on their mobiles. The company gave little away before today's event in the US about its "new home on Android", but it could mean a new homescreen for many smartphones.
The launch of an "enhanced app" will reinforce Facebook's "mobile first" as users increasingly monitor the social networking site from smartphones and tablets, rather than desktop computers.
