If you're a mobile blogger, you'll be happy to know that you can update your blog with your phone. It doesn't even have to be a smartphone, it just needs the capability to send and receive text messages. You just have to send a text to BLOGGR and you'll get a registration code that you can use to either create a new mobile blog, or link to your pre-existing Blogger blog.
Once registered, you can send photos and text to your blog via text message. The whole process and list of commands can be found at Blogger on the Go.
