I just figured it out on my phone how to add a signature. Like you said, there are a lot of different variables and versions of the site but the one that I found that works correctly is the "Enhanced Mobile Version" then go to the bottom of page and click on "Full Version" and you will be able to access the User CP and add or change your signature and avatar and so on.....
