Frequent IRC’ers on-the-move will be appreciative of Mbranes’ colloQ. It’s a new IRC client inspired by mColloquy for the Mac. You’ll get everything that has to offer plus bug fixes and further enhancements.

colloQ is currently available via Installer.app using the ModMyiFone source — http://modmyifone.com/installer.xml.

ColloQ features:

• More notifications are visible: joins, parts, nick changes, etc.
• Channel/PM timestamp
• Activity notification on main chats screen
• Channel member list allows access to user functions:
• Start/Resume PM
• Op, Deop
• Ban, Kick
• PM views now include a "Close PM" button
• Fonts and icons are now smaller – screen real estate is precious!
• A number of "slash" commands are available:
• /join <chan> Self-explanatory. The channel will appear in your main list. Example: /join #iPhone
• /raw join <chan> password I forgot to add password support to the /join command, but you can use this raw command as a workaround for now.
• /me <text> Sometimes referred to as an "action". Example: /me throws a hissy.
• /msg <nick> <text> Sends a PM to <nick>. Example: /msg nickserv help
• /query <nick> Opens up a PM window to <nick>, but does not send a message. The window will appear on your main chats screen. Example: /query JoeBlough
• /nick <newnick> Changes your IRC nickname. Example: /nick NewNick
• /ns <cmd> A shortcut for /msg nickserv. Example: /ns identify mypass
• /cs <cmd> A shortcut for /msg chanserv. Example: /cs set #iPhone desc A channel.
• /ms <cmd> A shortcut for /msg memoserv. Example: /ms read 1
• /os <cmd> A shortcut for /msg operserv. Example: /os help
• /raw <txt> This is a special command that sends text directly to the IRC server. It is like the /quote command found in other clients. With it you can send any command that the IRC server understands. Example: /raw links. (If you really want to see all of the commands that the server understands, take a look at http://www.faqs.org/rfcs/rfc1459.html).
