Know who's calling your Android phone with Facebook Hello

The previously rumoured Facebook app that can block callers is now official. The social network debuted Hello, an Android caller ID app. The app shows you the Facebook information your caller is willing to share with his or her friends on the site. The app also shows you how many times the caller has been blocked and automatically block those who are repeat offenders. At the moment though, the app seems to just be available in Brazil, the US, and Nigeria. No word yet when it'll be spreading to other countries but we're pretty sure that'll happen soon.
