It happened automatically for me. I'm on Verizon, and the icon to install was already on my app list. After installing, the same icon was used to access it.
I'm having the same question about this as BB Messenger (if it costs to use it). Does sending messages to your friends on facebook cost like a text? I'm under the impression that this is data use. We'll see when the bill comes.
