If you can not take the unit apart to dry it out then open the battery door and remove the SIM and mini-SD if present. I am assuming the battery is still out. Then use a fan to blow air in through the open door. Use tape to hold it open if you need to. Let the fan run for a day or two before you try to re-install the battery. You may be able to do further disassembly before using the fan to dry it out. I think you may be able to remove the plastic part at the top (where the camera is). Just do as much disassembly as you can so it will dry out better.
Then, take a deep breath, say a prayer or do whatever you do for good luck, install the battery and try to turn it on. May the Force be with you...
