Phew, back online (wired, but better than nothing) for the time being.
Cali, I have the Samsung Razr knockoff called the Katana. I don’t like it much. But you can do this with any phone that can send text messages.
Shel, you set it up at the Blogger Dashboard. In the right hand sidebar there is a link about Mobile Blogging. You follow it, text a message to the address shown, and it sends you back a code. You enter the code and it sets up a new blog for you. The next screen asks whether you want your texts to go to the new blog or your old one. After that you are all set.
