UILCDBackground.png has now become BarLCD.png or retina(BarLCD@2x.png) and goes in the com.apple.TelephonyUI folder.
You can also get Lockscreen Clock Hide from Cydia which hides the BarLCD.png image as well as the time and date from lockscreen. Has configuration thru Settings app.

Awesome Thanks so much ! I have been going crazy trying to figure that out!
