I too just loaded Applocker on my iPhone 4S and am now totally locked out. I was not given a choice to enter my own password or had not gotten to that part yet when I closed out and then all of the sudden all my apps were locked by the request of a password. The previous post said to use "password" but that is not working. I need help. I can't access any app on my iPhone unless I enter this unknown password. This is my own phone and I feel stupid for doing this.
