Thanks to BignaDad for figuring this out on Manila 2.5 and leading the way. The only problem is the file that is modified is one that gets modified alot with different mods floating around. So the best way to do this is to point you to the tutorial here:

The difference with 2.1 manila is that we have to modify the file named 1c684cd8_manila
You need to still have the blank logo cab installed for all of it to be blank, attached at the bottom of this post unless you change the coordinates of the carrier logo to something outside the viewable area.
Lastly, if you just cant figure it out post your 1c684cb8_manila file on this thread and I will do as many as possible.
