BerryOTA

Blackberry Messenger is a PIN-based instant messenger program that sends a message to other Blackberry users through their PIN number. It is based on the popular instant messenger format, and is very easy to use. It is indeed a great tool, especially if many people you work with have a Blackberry also.

One nice feature is the ability to chat as a closed group, such as a team at work. You can simply create a group list, and chat away.

In testing, the messages go through fairly quickly, and will alert you via a vibration when you receive a new message.

One note: you must have Internet Explorer 5.0+ to visit the website on a desktop. Otherwise, you can download it over-the-air (using Blackberry Browser).
