Ok after some good hard searching I Finally was able to change the carrier logo from t-mobile to the Halo 3 logo using customize the latest one.

also just incase you guys were wondering I'm on a 1.1.1 unlock with anysim 1.1.0.

Remember Customize will crash the first time you open it. I don't know why but it does and after that it seems fine. some of the customize feature didn't work for me like the weather icons.
