Where did you last see this executable?
I looked in the WM6.1 OEM RAR and the PPCGeeks OEM RAR and didn't see a file that matched the description you provided. I'm not saying you are wrong or confused; just that the things at my fingertips aren't particularly helpful to you.
The last place I can think to look is in the Sprint Touch ROM that ImCoKeMaN put together as part of his initial 0.3x unlocker test package. I am downloading that now.
