Winterboard UIimages help

[superxero3]

What is the name of the picture that is the black transparent background behind the "End Call" button when on a phone call?

anybody? i'm trying to make this transparent, and i don't know what the name of the image is (i'm also making the assumption i have to use winterboard to theme this image)

also, is it possible to skin the keyboard without winterboard?

I don't know but there are a lot of images in /System/Library/CoreServices/SpringBoard.app and /var/stash/Applications.FiaIgy/MobilePhone.app.

/System/Library/CoreServices/SpringBoard.app/LockScreenControlsHUD.png looks like a possibility.
