You can now unsend your Facebook messages if you're quick enough - Mashable.com

Facebook Messenger is finally rolling out the unsend button it promised nearly a year ago. The feature is in the latest version of the Messenger app on iOS and Android, Facebook said Tuesda, as Mashable.com informed. In order to exercise your newfound message deletion powers, all you have to do is tap on a message in a conversation and select "remove." The app will then ask if you want to remove the message for everyone or just for you (the latter keeps the message visible to other participants, while hiding it from your view). There is, however, one important catch: you only have a 10-minute window to delete your messages. Once ten minutes have elapsed, you're stuck with your embarrassing typo-ridden messages forever.
