Just wanted to right a quick guide on how to change the statusbar icons to any other carrier since I have not seen this anywhere. Some people may like them a little better then T-mobile. I have seen mods that do this but it is actually as easy as a few build.prop changes.
Please note: These may cause more subtle changes as well since it basically fools the device into thinking its that carrier. The main change is the data icons, but some carriers also put there network on the left of the statusbar (at&t) and other things
Just simply use a file manager with root (recommend ES Explorer) and navigate to /system. Then open up the build.prop file in a text editor (after making a backup first of course). All you need to do is change the following lines to whatever you would like..
