Okay, so I have an LG Rumor-just got it today-and have been playing around with it. I want to know how to lock it so i can only unlock it with a password. I think I found a way, but it takes so long so I was wondering, can I set a key on my phone (or is there already one) to lock my phone with a password so I don't have to go through the process of going into the menu and stuff every time?
