da-mini protector ... fits like a glove (literally ... you gotta sand a fraction off the shorter sides for it to fit snugly). The protector doesn't cover the entire LCD (about 0.5 cm not covered), but that's ok, the plastic on the protector is thick, so you will unlikely damage the LCD plastic even where it's "exposed".
One of the best things you can do for your S2, and time to get rid of the horrible translucent white cover.
