Dunk it in FRESH water (damage is done) then shake it out. Put it under a fan or a light bulb and see what happens. Dunked mine and did that...worked fine until I dunked it again...then there was no coming back
What ever you do don't get Nextel, worst service I have seen,
Verison seems to be best, trash that phone and buy a new one
I have gone threw everything with over 7 phones and nothing is
a cure-all
