How much does it cost to unlock an iphone 4 with verizon?

I'm buying an Iphone 4 off of someone, but it is under Verizon. How much would it cost to get it unlocked? I can also go to Main St flushing. How much would it cost there?

Verizon should unlock a phone for free. As long as the contract has been fulfilled for the plan it was originally taken out with.

He buoght this phone so can't hae contract with verizon

but you can buy unlock services for it on ebay at 5-8 bucks
