You can get the same effect without a Cydia tweak. If you have iFile navigate to System/Library/PrivateFrameworks/TelephonyUI.framework and EDIT the names of BarBottomLock@2x~iphone.png & BarLCD@2x~iphone.png by pressing the arrow on the right side. I usually just put 5 x's so it's easier to find again. As for the slider I'm not sure if you are already using Winterboard and own themes might just be easier to extract the 3 files and use them. Here are the names of the 3 files. bottombarknobgray@2x~iphone.png, bottombarknobgreen@2x~iphone.png & bottombarknobred@2x~iphone.png. Hope this helps a bit...
