What should you do to fix a home button on your iPhone 3 after you dropped it in water and it stopped working?

One of the best home remedies to prevent damage from a technological device after it has been dropped into water is to not turn it on to begin. This could cause internal damage and you would need to take it to a repair shop to have it fixed. Disassemble the device, i.e.: Phone, back, battery, then place them in a bowl of rice overnight. If the device has been wet and drying out without rice or something else with similar properties, you may have internal damage and need to take it to a repair shop.
