Nokia c3's do not have a facebook chat but they do have facebook. Try a blackberry crve 8520 its great and they have a facebook chat.
well usually when someone is online it will show up in facebook chat. however facebook chat isn't always accurate. and since phones usually don't have facebook chat, the only way to really know is by recent activity.
Post on their wall, send them an message.
