Soon you'll be able to edit and unsend iMessages on iPhone. Here's how it works

1SG (Join to see) "Reports indicate that users will be able to hold down sent messages to receive an options menu, and inside of this menu, there will be the "edit" option along with the "unsend" option. The new feature has already been rolled out to the public beta, which is available to download right now if you choose to opt-in."
