Wired Magazine has a blog post up on their website about Second Life running on a phone:
In keeping with the theme of the past two weeks, and alternative clients for Second Life, here’s a new one that runs on a phone. The interface allows some basic Second Life functionality from your cell phone. There’s even a video of it in action on a phone. The company providing this is Vollee. Load times look very slow. You can teleport, walk, fly, have access to your friends list, and chat. Not sure what else you’ll be able to do at this time.
There’s a free open beta signup at http://www.vollee.com/secondlife.
For a first of its kind, it really doesn’t look too bad.
