This post is useless if someone has the knowledge to replace the battery they ought to know how the home button works "gold prongs". What is the resistor next to the u3 chip? That's kinda important if you want to order one and how do you replace such a small resistor (small chip size). I'll try to get back if I ever find the real solution and not "bad home button" arrg! the battery replacement doesn't effect the home button! Btw if you need a work around you can go to "settings-general-accessibility-AssistiveTouch-on, and that will give you a home button on the screen (software) - it's a pain in the a** but it's a work around for now.
