Its weird why Facebook didnt develope a messenger application sooner, you can find all sort of apps on the Android market which lets you use the messenger chat of Facebook, one of them, which i usualy use is Go!Chat.
Today, Facebook Blog announced, the messenger application for mobile phones, will come soon for Android and iOS handheld devices. The application is meant to simply the way we write and send messages.
Everyone knows Mark is a big fan of Iphone 5, what i cant figure it out why the announcement has only screenshots from an Iphone device and there is none from an Android device. BUMMER!!
Update: The app is now available in the Android market just click this link and get it, or just search it on your market app.
