Google Buzz works on iPod/iPhone, even if not in your Gmail or Google Apps
I am a Google Apps Standard user, so I don't have Google Buzz available in my email account and apparently there are a number of normal Gmail users that still don't have it available. A friend of my tried buzz.google.com on his iPhone and it worked even though it doesn't work in his Gmail on the computer. So I thought I would give it a try, even though Buzz isn't slated for release to Apps users for months. Sure enough, it worked!
