I'm not too surprised that this exists honestly...A security hole in iPhone 4 software allows you to make a call after dialing a few pound signs and timing a few others as found by a MacForums member.
When you iPhone is locked with a passcode tap Emergency Call, then enter a non-emergency number such as ###. Next tap the call button and immediately hit the lock button. It should open up the Phone app where you can see all your contacts, call any number, etc.
