TigerText – Secure Mobile Messaging
http://www.tigertext.com/

When sending a regular text message or picture over mobile phones, you have no control over how long it will live on the recipient’s phone or the cell phone servers. TigerText is different because, even though it looks and feels like a normal text message, the sender controls when the message is deleted. Reclaim the privacy of your text messages and pics!
