Glad to hear that it's working again!!!!
If it ever happens again, I would suggest that you remove the battery and SIM card, then wash the whole beastie in fresh water... soak it and shake it under water to rinse all of the saltiness out, and then soak in rubbing alcohol (the alcohol displaces a great deal of the water) and put on a heater or in a dehydrator to dry out.... it's worked for ever phone that I've ever dumped in the water...
