I think when you press "W" on the keybopard a shortcut pops up with bevel and such and one of them is set smoothshading i think..I think also in like the menu on the bottom, while your in edit mode, one of the buttons down there says set smoothshading. (maybe in sculpting?)
That's easy go into edit mode press set smooth then after that press smooth till your liking it.
Ive tried selecting the mesh and clicking "set smooth" but it does nothing.
Lol. Thanks for trying to help though, dude. About what you said about the bones, I actually thought so myself, but the set smooth button dissapears when I select the bone. Any idea about what else it might be?
