I did used to have a program on my old Samsung i300 that made it LOOK like that's what you had. When you woke up the phone, you pressed down for "access denied", or up for "access granted" then put your finger on the screen. You always made sure to hit down first, then hand it to your friends and watch them "marvel" at your "technological acheivement". Maybe you should look for that app. Probably still work on most POS phones.
