If you own an HTC Hero, Magic or T-Mobile G1 and you're partial to a little text chatting on the run, then read on and watch the video. Today one of our favourite mobile instant messaging services, Nimbuzz, launched an app for Android users. The Nimbuzz Android app allows users to message each other using ICQ, Facebook, Google Talk, Skype, Windows Live Messenger and Yahoo! Messenger. It pops up home screen notifications when you get a message and, unlike the iPhone version, can run in the background.
