Answer to: iPhone 4 vs iPhone 4s home buttonI've been having a lot of problems the last few days because I ordered a cheap claimed-to-be iPhone 4S home button from China but it wouldn't fit. I kept searching for what I was doing wrong but couldn't find it. Then, I ordered a original 4S homebutton, as well as a original 4 homebutton. Turned out the so-called 4S button was a iPhone 4 button and that was why it wouldn't fit! The authentic 4 button was better than the fake 4 but not nearly as good as the one for the 4S. Note: I tried every combination of spacers and gaskets and whatsoever, it really was the homebutton causing the trouble. Concluding: A iPhone 4 homebutton WILL NOT FIT an iPhone 4S.
