Are u tired of people reading your text messages? This software allows you to send encrypted text messages. You n your friend agree on the password u will be using then send the text. It is a must for both of you to have the software or else the recipient will not recieve it because it will have been encrypted. It works in most java enabled phones. If u have a phone with MIDP 2.0 the software will open automaticall but on 1.0 you will have to acess the software to open your inbox. Otherwise it wil be like you normal inbox. Works in all models.
