Samsung :: Phone Not Hold Any Programing

My brother dropped his phone in the sink while he was shaving and now he wants me to fix it. Anyway, phone still works fine but it will not hold any programing. I called the *228 and it said it succesfully programed and the phone restarted but its says its roaming but its not. Make a call and it connects you to an operator wanting to assist you in making a collect call. I called verizon and manually programed it and still the same thing. After the restart, the phone number in network settings goes back to something that isnt even from around here. The home sid/nid goes back to diffrent values than what verizon gave me. Meid shows all zero's. Anyone have any ideas on what I can do to fix this?
