There could be damage/corrosion on the home button circuit or on the dock (The home plugs into the dock module, which plugs into the circuit board). If you are comfortable and have the tools, you can open up the phone and have a look at the dock to see if you see nay corrosion. Examining the home button circuit will be a little trickier, as you have to completely take the phone apart to see the entire home button circuit. If you do see any corrosion, you can attempt to clean it using a brush (like an old tooth brush) and Isopropyl Alcohol. If you are not so comfortable with taking it apart, there are several repair company's out there that specialize in iPhone repairs and would be able to help you. They are just one Google search away.
