A couple times a day my iPhone 4 will not do anything when I hit the home button (it immediately works upon hitting again ) and will pull up multi tasking when I click the home button once. I am Jb on 4.0.1. The fact that this only happens a couple times a day, and not consistently leads me to believe it's amsoftware issue. Could it be activator? Any opinions?
