I've searched everywhere for changing this background, and the closest i've got was a file called default-smsanswerbackground.png or something of the like.
Has anyone stumbled across the actual background for SMS/Messages app? I'm thinking that it's either in an artwork file, or a resources file, maybe even a plist somewhere, but I can't quite find it.
I'm sorry if this has been posted, i'm just anxious, and can't find it through the strict searching rules.
