App to turn-off display during calls?

[Modulus]

My Samsung i730 had this feature built-in. The Spring Mogul doesn't appear to. For a while I was running S2U2, mainly for this feature. I don't feel like installing it again, now that I have a fast/clean, recently updated device.

Anyone know of an app to kill the display during calls? I've tried registry edits, Advanced Configuration Tool, and a few other things with no luck..

S2U2 has a setting that does that for you, as well as other screen blanking and slide to unlock features.
