Help Desperately Needed

[Silent Assasin]

I recently had an accident where I fell down and I beleive that I broke my PPC 6700. The Screen is totally black except a purplish blot on the upper right corner of the screen and I beleive I can see a hair line crack underneath the main screen. I tried a soft and Hard reset with no changes. The question I have is how do I reset the phone to original settings without the phone working? I can't turn the phone into Sprint like it's currently configured due to all of the "additional add-ons" provided by this great site! What should I do?
