Nokia 6111

Question

I havent had much luck with mobile phones lately, you solved my problems this today and I was very impressed.
Last week I dropped my Nokia 6111 phone in a bucket of water I immediately took it out and dried it as much as possible. I dried it with a hair dryer an left it open for a day or 2. It seems to work for a while then swithches off, and if I switch it off it and try and switch it on again it doesnt come on basically what I am trying to say its just not working as normal.
Do you think it could be repaired?
cheers
