Okay I just purchased the app based on great reviews. I was provided with an activation code, but for the life of me I can't figure out what to do with it. I can't find the program anywhere on the phone. I know it's installed though because when I'm on a call and I hit the menu button there is a new option that says Lock phone or something like that. However it wont let me use it because it's not registered. Is there something that I'm missing here?
