How do you unlock your LG Rumor phone?

if you're talking about when you turn it on and you cant do anything except call emergency numbers then you enter the last four digits of your phone number or who ever's phone it is. but if you're talking just about the screen being locked then you can either press a button to light up the screen and then touch where it says "touch to unlock" or press the lock/unlock button which is on the left side of the phone and at the top.
