Crimson Fields is a great turn-based tile strategy wargame based on an old game named Battle Isle. It's freeware, not warez, but I don't think most people know about it. It is my favorite SmartPhone game so far.

http://crimson.seul.org/index2.php Hopefully there are good instructions on one of those sites, I remebered enough of the original game to be able to figure it out by trial and error. Some important functions are assigned to keypad numbers: repairing things and tranfering crystals to/from transports inside depots, going inside transports to move things out, etc.
By the way, this is a great source for freeware and demos:
