hi my daughter gave me her old iphone 4 ,if i could repair it the on off button was not working so i striped it and replaced it ,i remembered then that her home button did not work [she had home button software installed on it]we can not remember the passwords or id for it ,is there a way to downgrade the firmware before this stupid apple update that you have to activate it,i know its a good thing if your phone is stolen but a pain when this happens any help please
