I used the original button. I cut little pieces of electrical tape and placed them over the metallic clicker so the button could hopefully make better contact with it once I installed back the small circuit board. The tape also held the clicker in place but it was still a pain trying to align it. The only issue after installing the circuit board is that I no longer got that 'click' feeling from pushing the button, but it does work.
Dude you rock. The information that you supplied is priceless. thank you... now do I want a click or not.. its for the kids so I most likely wont. I did one of those jobs on a itouch before and cracked the screen. you gotta be real careful. Thanks MOF
