How to release screenlock on BlackBerry Storm

I just bought a new BlackBerry Storm 9530 and I push lock icon on the screen. After that I don't know how to unlock it and try to explore to unlock my BB.
Finally I found a small button on the top left of the unit to release this screenlock.
Hopefully help.

Cheers.
