jmIrc is a an open source J2ME MIDlet allowing Blackberry and cell phone owners to use IRC wirelessly. IRC stands for Internet Relay Chat, a chat system that enables people connected anywhere on the Internet to join in live discussions. It is programmed for use on all MIDP 1.0 devices, thus it will work on the Blackberry but does not utilize Blackberry specific features.
This project started as a fork of Sverre ValskrÃ¥’s WLIrc but eventually led to be a complete rewrite project. Its aim is to be as small and lightweight as possible still trying to maintain the ease of use and all needed features. At the same time it tries to be some kind of hybrid implementing all the most useful features from other clients.
