You don't have to jailbreak your iPhone to switch to Sprint. Just cancel your contract with Verizon and got to a Sprint store with your phone. They will help we step up your phone with them.

You don't need to jailbreak your phone for switching it from Verizon to Sprint. You've to get it flashed to Sprint and that doesn't require any modding on your phone. You can mail this person (arghyle@rocketmail.com) who can help you get the phone flashed from Verizon to Sprint.
