broken home screen button replaced successfully and working like new

Mi Problema

My home screen button was working maybe once out of every five times i pushed it

Mi Solucion

the truth is i had my friend do it for me since he recently took his own iphone 4 apart. he would double check with the instructions from ifixit when he wasn't sure of something and the whole thing went pretty smoothly. after replacing the button and ribbon it was working like new

Mi Consejo

if you've never taken your iphone apart be EXTRA careful. if you have a friend who has more experience with it then ask him/her to do it
