I've setup an irc chat room on gamesurge.net. You can come and chat with your friends, setup games, recruit for clans, etc etc.
Information
server: irc.gamesurge.net
channel: #n-gage
If you need an irc client I suggest mIRC: www.mirc.com
if you don't want to bother you can use the java applet at: www.dmorandstuff.com/ngage/chat.html
