Facebook Messenger for iOS has just received an update that lets you create group chats (via Engadget). As in other versions of Facebook,_you simply name the group, set a photo and chats will be gathered together in one conversation. You can also “pin” groups to get easier access to them. The latest update also lets you forward a message or photo to someone else who isn’t in the conversation, and has “continued improvements to make the app faster and more reliable.”
