Actually, for the iPhone 4S, Sprint originally didn't lock it, but later did lock it to prevent it from working on US GSM networks. There's an MCC block on the Verizon model as well for GSM networks.
Just because the bands are supported doesn't mean the carrier will let you use it as they should be. Remember Apple won't let you use any LTE network you want, only ones it has tested and approved.
