How much locking a phone changes it from an unlocked phone?

Answer 1

There's really no big difference when you unlock the phone. The functions, applications and features of the phone will still be the same. The only thing that would change is that you can use different SIM cards from any GSM carriers on the unlocked phone since the restriction is already removed.
