Unlock Nokia 1110

I never knew Nokia cell phone’s security was this lame. I have a Nokia 1110, which I had locked using the security code. Though my sister didn’t know the code, the easily unlocked it.
You can try that too. Its really easy:
1. Use 2 hands.
2. Keep on pressing Unlock for around 2 seconds until you see press *
3. Quickly press *
