I was just reading a post where someone wrote that, if you call TracFone, they will carrier-unlock the phone for you. I have not tried this myself, though. For root, try KingRoot, KingoRoot (note the "o" in this one), etc. Be careful, though, as I have heard of some (stock) phones not booting after being rooted. Better safe than sorry.
