Sony Ericsson W810

hey i was reading through different threads on some other website. i came across a post regarding how to remove the service logo. for example i use tmobile .so it says "TMO" on top in white the whole time. i can get annoying at times. But anyway, that process seemed a lil too wierd and risky.
My main question is does anyone know how to remove the service logo from this phone?
thanx
