Christina solved a problem I would bet at least 80% of us have faced. Your mileage may vary, but it's worth a shot:
My son has a fascination with my cell phone. He likes to talk on it. He likes to press the numbers. He likes to store weird names in my directory. But he also likes to suck it and drool on it, so much so that he was able to get the inside of the phone wet.
I could only use the earpiece and the phone company said that there is nothing that can be done about wetness in the phone. BUT…I remembered how quickly my soup I left uncovered in the refrigerator dried out just days earlier. I stuck my phone in the fridge for 24 hours, and it came back as good as new.
If your phone ever gets wet, stick it in the fridge. It dehumidifies.
