Believe it or not, Facebook has just released an official Poke app for the iPhone.
The app lets the user send a photo to another user which is only be viewable for a short time. Something like a self destructing bomb in Mission Impossible.
Poke your friends to share fun moments or just say hello.
• Poke a friend with a message, photo or video
• Choose how long they can see it
• Press and hold to see pokes from friends
• Say where you are when you poke
• See when your friends take screenshots
