To use an unlocked phone with a differert provider you will need to get a SIMM card from them and put it in the phone.
I am not certain but I believe in order to get the discount on the unlocked phone you need to activate it now with one of the three carriers. You may have to lock into a contract with the carrier to get the discount. I believe the discount is offered by the Carriers and not Best Buy.
