I don't think you can, Sprint and Verizon use two different network technologies. You might get lucky if its an international version but you need a Sim Card slot for it to work on Verizon or AT&T.
Verizon and Sprint both use the same technologies, CDMA. They contain the same exact hardware haha
Yes but the phones underlying software (think of a PCs BIOS) can be locked to a certain carrier. By changing those settings the phone can be used on any carrier.
HOWEVER. We do not discuss how to do this here. For one thing, we can't prove who owns the phone. We will not help commit theft. Secondly, if the phone was purchased outright at the carriers store, they would have unlocked the device at the time of purchase. This means the phone is or was intended to be on a contract. If the terms of the contract were or are yet to be fulfilled, upon fulfillment of that contract Sprint is required to unlock the device.
Alternatively, you can pay a large fee to have the device unlocked by Sprint if the contract was broken or if you want to end it prematurely. The fee with most carriers is typically $40/month remaining in the contract or $400, whichever is more.
Anyways, I'm closing this thread since discussions of this matter are frowned upon due to the reasons I've outlined. For future reference there is a sticky all about this at the top of this forum.
