With Facebook Chat we can chat from our Nokia 5800, Nokia 5530, Nokia 5230 and Nokia X6, with our Facebook contacts. Simple and practical application with an intuitive interface with which to communicate with our friends instantly.
Another application to chat with your contacts in Facebook is FriendChat, which has been revised and improved and is now more stable in the new version 1.0.36. Personally, I prefer the latter.
Facebook Chat is available free at Ovi Store.
