Recommend me some WW2 strategy games

[zombied]

So I really want to play some WW2 strategy games on my iPhone. Most of them are really nothing but Risk clones with varying degrees of depth. I want something unique and fun, and since I love the subject matter, the more detail the better. I'd like to avoid those infantry < vehicle < tank-type simple dynamics that are just a WW2 skin on a pretty standard game.
