Remove the battery and let the phone dry out for about 5 days. If you can get it apart to speed up the drying process, all the better. Once it's apart as far as you can get it set it on your TV or stereo or somewhere that stays warm. Then put it back together after it thorughly dries. Water doesn't damage the phone. Water AND electricity damages the phone.
You've removed the liquid indicator so your warranty is void anyway. They can tell the device has been wet anyway. You won't get a new one under warranty.
