iRCm for iPhone with 2.0 firmware
IRCm is a GUI-based Internet Relay Chat client for the Apple iPhone, by Chris Lott (aka pogi) and Nicholas Penree (aka drudge). The app is pretty rough, but for the most part works as it did on 1.1.4.
It is the first and only GUI iRC client for iPhone 2.0. Note: this is ported from SVN 36 in googlecode.
