I came across ICQ and was surprised to find that it has faceboook integration.
I have tried different facebook messengers- the built-in one(which is good but has stopped showing online contacts),IM+,facebook beta messenger but none as good as ICQ
ICQ is quick,responsive and does'nt heat up the device and drain battery
ICQ also supports Gtalk. Try this app and u would'nt want a better facebook messenger
