Root Removal of AT&T boot screen?

[theadderblack]

Hi all. I'm working with Firefly 2.1 which I'm loving so far (gotta get used to the up and down 3D style apps gallery) but I'm still seeing the AT&T World Phone white splash screen when I start up my phone (the very first screen I see).

Is there any simple way to get rid of this or perhaps replace it with a screen of my own?

Thanks all!

Anyone? Beuller?
