Answer to: iPhone 4 vs iPhone 4s home buttonIve taken apart my old GSM iPhone 4 many times, but I haven't taken my 4s apart to inspect it up close yet. The ifixit teardown pic shows the home button now attached to the front lcd assembly by some kind of mounting unit. On the iPhone 4, the plastic button was stuck to the flex cable with adhesive, which was plugged into the chassis. The front screen assembly just had a hole in it where the home button protruded through. Now it appears that the cable is on the chassis and the button is on the front panel, and they just press together in the middle when the front assembly is attached to the chassis. Anyone actually taken a look at this yet? Can that new home button assembly be removed and transferred to another screen assembly?
