well, I had my Razr immersed in beer on Grand Final day last year (or was it 2 years ago)- it did not work when I woke up, nor did it work 3 months later or 6 months later.
It works now - 13 to 14 months later.
What I want to say is (and I read evidence about that elsewhere) it can take a LONG time to get the inetrnals to dry.
The fact that it did get hot etc - you may have no luck!
Time will tell, and if you sell it, I recommend - be honest - you have live with yourself! YMMV as are your values
