Not all CDMA Carriers are this way, for example all Verizon smart phones come from the factory unlocked for use with all carriers(including iphones). You can unlock a sprint phone by obtaining a code from sprint but they don't like to give them out unless you're a good long time customer, however even unlocked most sprint phones still have very little usability with other carriers other than the iphones. An unlocked sprint iphone can be used on any carrier. I hope this helps.
