On Wednesday, developer 3V released Locker, an iPhone application that allows users to send and receive encoded text messages (for example, “Want to meet me for lunch?” can become a seemingly random stream of text).

Once the message’s recipient receives the encoded message he can just paste it into LOCKER and decode the message.

Locker retails for $0.99 in the App Store and requires iPhone OS 3.0 or later to install and run.
