Campfire has officially announced that Campfire has been optimized for the iPhone. To see the iPhone version you must visit your Campfire site ( http://YOURSITE.campfirenow.com) with Safari on the iPhone and you’ll automatically see the iPhone optimized version.

The iPhone version starts in the Lobby where you see your list of chat rooms and allows you to chat with the people in your team using an iPhone Ajax powered interface. For more details visit the Campfire blog post about the iPhone support feature.

Note: If you are using a non-iPhone browser you will still see the regular Campfire site.

You must be using an iPhone to see the iPhone version of this app. Try it here
