How/Where can I unlock my verizon iphone 4?

I have an iphone 4 from verizon that I want to unlock to use on sprint and I can't find a decent video on youtube that is actually legitimate! This phone has no sim card so any sim unlocks will not work. And if I can't do it myself, where can I get it done?

Regrettably you are tied to Verizon. Their system ensures you are locked in. Avoid Verizon like the plague!

You have to own the phone to legally unlock it. So if your contract is up with Verizon and the phone is paid off, you call them and they will give you instructions on how to unlock it.
