I noticed that the recently updated Facebook for bada app’s Chat is now working fine. You can see everyone who is online and chat with them in real time.
You will also get a Facebook notification on your phone when the app is minimized whenever/whoever PMed you through chat (as long as you stay online or logged on to chat). I’m using 3G connection when I took the Screenshots.
So you can go ahead and see what are the differences and in this new update.
