If you haven't plugged in the phone and it hasn't actually blown anything, then put the phone in a bag of rice and hope that all the water is soaked up.
I have a huge touch face deck in my car and spilled 2 drops of coffee on my stereo. For a week it wouldn't turn on at all. I took off the face and stuck it in some rice, next day I tried it one more time and it worked...sticky....but it worked....
Then I rinsed it off in rubbing alcohol and it cleaned some of the sticky sugar out. Save me a $600-$800 car stereo.
