I agree with weedahoe. If this persisted after a hard reset on 2 phones, its not your phone that's the problem. I would take it back to Sprint (go to a store with a repair center so there is at least a technician there that has a little bit more of a clue), demonstrate the problem to them in person, and see what they can do. Hopefully, its just as simple as reprovisioning the device.
