Help protective case with screen protection for samsung galaxy S2

[tiny_bits]

hi

I've seen a lot of protective cases, but I'm interested in a protective case that has something going over the phone's screen.
I need something that will protect the screen in a case it falls face down on a set of keys with the keys in the center of the screen.

example of what I am looking for is the "otterbox defender":

or the "phantom case mate":

those two seem to be available for S3 but not for S2
I need something similar for S2
