Looks like the BlackBerry PlayBook received another Google Talk 3rd party client.
Chat with your Google Talk friends from your sofa on your BlackBerry® PlayBook!
This application let you connect to Google Talk, view the status of your friend and chat with them – that’s as simple as that!
This is still a BETA version, so some features are not yet implemented and there might be some bugs. Feel free to contact me if you find one!
Get this client via App World.
