IPhone in water. What do I do?

My brother dropped his iPhone in a cup of water. I dried it with a paper towel and put it in a bag of rice. Anything to do or not to do?

Put it under sun light.

Use a hair dryer.first switch off the cell.

Put it into a box which is full with rice.

Did you turn off the phone right away before wiping it with a towel and placing it in a bag of rice? Then just leave your phone covered with rice for 24 to 48 hours. One thing you mustn't do is to blow dry your iphone as it may melt the circuit boards and other parts. So far you are doing the right thing.
