If you have an iphone, palm pre or a mobile that runs on Google's android system, you can check out the latest Greenpeace guide to greener electronics on your handset here: http://www.greenpeace.org/electronicswebapp
Nidhi, one of our new communications interns, made it the other day. Called a "mobile webapp", it's really just a webpage with some fancy javascript and stylesheets (from jQTouch).
We published the latest edition of the Guide to Greener Electronics last week, and silently launched this mobile version too. There are some bugs still, but for a few hours work it'll do the trick. (If you know how to fix the twitter status bug, please leave a comment here! Other suggestions also very welcome!)
