It's rumoured that Whatsapp is going to let users delete messages they've already sent.
People with jailbroken iPhones claim to have accessed a test version of the app, where "revoke" and "edit" appear as options.
It sounds perfect for the morning after the night before, but at the moment this is all speculation - with no official word from Whatsapp.
It got us thinking how different 2016 could have been if it already existed.
