Two weeks after Facebook introduced stickers on their mobile messaging app for Android, the feature is now also available in the iOS.
You can now update your Facebook Messenger to 2.4 from the App Store to get this feature. There are a couple of sticker sets included in the update but you can download some more from the Sticker Store. As of right now, there are a bunch of critter sticker sets available for free download so you might want to get them as well in case Facebook decides to add a price tag to them in the future.
The stickers are not available for those who use their web browser to chat, but they will be able to see the stickers sent from Facebook Messenger.
Also included in this Facebook Messenger update is the swipe to delete a message thread from your inbox.
