The application, already available on iPhone and Android, has also arrived on BlackBerry.
Facebook Messenger now shows application users on iPhone, Android and BlackBerry which of their friends are online or available via mobile, and makes it easier to send messages to the folks they communicate with most frequently.
Better still, the updated application now shows when a user's Facebook buddies are typing, an experience that emulates BBM, iMessage and Facebook's own web messaging system.
The Android Facebook Messenger app also now includes support for 22 additional languages, and the iPhone app has added 12 new languages.
The application, based around group messaging app Beluga, a startup Facebook acquired earlier this year, proved to be an early hit with iPhone users. With the update, the social network is demonstrating an ongoing commitment to real-time communication across multiple platforms, and its app now better rivals Apple's and BlackBerry's single platform messaging systems.
