Is it possible to unlock a iPhone 5 on ntelos to get on sprint service?

I recently got a iPhone 5 and It has ntelos service on it. I want to get rid of the ntelos service to get sprint on it. I guess I'm saying that I want to factory reset the phone so I can put my sprint service on it? Any way to do that? Without bricking the phone?

I don't believe that is possible without a real risk of bricking the phone. If you live in the Ntelos service area, Ntelos and Sprint utilize virtually the same towers and the cost is cheaper. Your service would be virtually identical.
