Bad digitizer and am rooted

[BiGsMiLeSKyLe]

Hey all, I wanted to ask everyone for their opinion on what I should do. I done all the resets including the factory, and any keyboard i have, the keys closest to the right side do not function. I am rooted and am on 1.4, though I want to get it replaced through sprint and I want to know am I going to need to reset my phone to stock to get it fixed? I had a launch day phone and this just sucks and would like to type on my keyboard without having to put it landscape.
