How to remove tf3d top bar

[thepgo]

I'm using Gen.Y TF3D. I'm happy with its stock look(only modified a clock and slider), but there is one thing i don't like:

That top bar marked with red arrows, i want to remove it, but don't want to apply any themes(to leave the stock look)
I've learned so far, that i probably have to edit some manilla file with CFC GUI. But exactly which one?

(if this is a dumb question, excuse me)

EDIT: I'm using Dutty's NoTopCurtain.cab http://forum.xda-developers.com/showthread.php?t=509360 and also the remove curtains .cab from http://forum.xda-developers.com/showthread.php?t=419799&highlight=curtains
