Trying to Tweak

Hey guys, I used to have an HTC Touch, with touch flo, and I had it customized, although the Pure's version is better then how the touch came originally, I really dont want to be looking at the At&t logo on every tab, thats my main complaint.. I have been digging and trying to find alternatives to this, and try to find the root at&t logo file and just replace it but have been unable to find it, any tips or suggestions is greatly appreciated.
