Hello, A coworker has a Iphone 4S 16GB white edition. The home button does not work as it worked on the old 4. When you open a folder and press the home button, it will not close the folder. When for instance on the second home screen and you press it, the phone would ussualy return to the first home screen. This does not work either anymore. Does anybody know a fix or is this as it is? Thanks in advance, SnoopNL.
