As I've mentioned on previous similar posts, it's probably still got a small amount of water in it.
I suggest keeping it switched off and placing your phone under a gentle heat source i.e. 60 watt lamp, over night, making sure the bulb is about 8 inches apart from your phone. I saw this method on the gadget show.
Alternatively, place the phone in your airing cupboard, (switched off), for a week. This fixed the same problem for me.
Also, if you can loosen the case screws in the phone (may need a tiny screwdriver bit avalible online), this will help speed up the drying time.
