What is there not to like about cell phone texting? Teens love it. But change the subject to studying and you have a whole different question. Now a text messaging company thinks it has the answer with eTextPrep, a new educational vocabulary and test prep service.

Smartly capitalizing on a teen's favorite activity, eTextPrep uses mobile phone text messaging to teach.

"Students receive two to three text messages per day that contain essential SAT/ACT, AP or Middle School Challenge vocabulary words, their definitions and parts of speech," said Lynne Anderson, founder and CEO of eTextPrep. "Students simply open, look and learn. It's mobile. It works."

Move over James Bond, there's a new secret agent in town, complete with self-destructing messages.

Look out for TigerText, a trendsetting mobile application that allows users to send text messages that self-delete from both the sender's and receiver's phone after a set period of time.

Designed to address growing concerns over privacy, TigerText lets you control what happens to your text message long after you hit the send button.

Once a sender selects the text lifespan, expired texts not only disappear from the phones, but are not stored on any server, according to the TigerText company. They cannot be retrieved once expired and they are not legally discoverable; it is as if the messages never existed.
