If you have a home button that doesnt act right or sticks when being pressed, then buy this part. Its usually not the button that goes bad, its the little flex cable that runs underneath. This is a pretty difficult repair, you have to remove everything inside the phone, pull the screen off, and then you can access the flex running underneath the homebutton.
This home button flex cable is not compatible with any of the other models of iPhone. As always we have a truly original iPhone 4s home button flex cable - long lasting and original.
