I've set up my gmail account on my phone, and I'm always logged in. I'd like to be able to log out in case someone happens upon my phone they can't just start going through my e-mail. I've read that you can delete cache and cookies to log out, but this seems to be a very crude way of doing it. I haven't tried it yet and would rather not. There doesn't seem to be a way to log out. Does anyone know how?
