Lets try this again. The cab I posted a few pages back had the wrong files in it. I can't make a cab right now but here is a zip file that has the two bmps you need.
This will change the color the HTC Menu from green highlights to a dark blue highlight that matches the t-mobile manila theme and tsk.
Just copy the files to your windows folder and soft reset. IF you think you'll want to go back to the green highlight, be sure to backup your files first.
