I don't believe the phone will prompt you to enter the unlock code until you try to use a non-ATT sim card. I may be wrong about that though. I've never tried unlocking using a code. However, I don't recall ever seeing an option to unlock the phone when I was running the stock ROM.
That being said, once the phone is unlocked, you can still use ATT service with an ATT sim card.
