For testing purposes the Mothership is now running the latest internal version of Jailbreak 2004, but the server does not allow to download files for the moment.
That means only the Jailbreak developers can currently play on the Mothership. Believe me, it's not all fun: we're chasing down any final bugs that may remain. We really want this version to be kick-ass perfect.
Update: Sorry, got my wired crossed. Sexmachine has disabled downloads, so I'm afraid you can neither join in nor watch if you're not a developer.
