How to reload WM5

[gdatkins]

Ok I did the upgrade to WM6 and it seemed to go find except for one small problem, my screen has a dead spot so I can not get past the align screen on the WM6 set up.
So I am guessing I have to take the phone into Sprint but I am sure they will not do anything with WM6 on the phone and blame the screen on it. So is there someway to reload the old OS? Or otherwise get past the WM6 set up?

THanks
