I downloaded and installed the Handcent SMS app to change the color of my texts and background etc. It downloaded and installed ok, but I can'g get it to work. I kept getting asked to register an account. I figured it wasn't one of the apps supported by VM. So then I tried Go SMS Pro, downloaded installed and got one of their plugins for the Purple theme I wanted. Everything downloads ok, but I can't open it and change the colors. Any ideas on what's going on?
