Dropped right in. You can see it here: https://skitch.com/cwsaylor/883te/font-awesome-phonegap

To get it looking really good, I'll need to play with the button padding and the font size. This is using mini buttons with large icons.

I also noticed that the thumbs up/down next to each other has the optical illusion of not looking centered.

Good call on the thumbs. I'll vertically center it better visually.
