How much would it cost to cancel my contract on Verizon?

Hi, I'm wondering how much it would cost to cancel my contract on Verizon? I have an iPhone 4, and on the website it says my contract ends on 7/09/14. I'm planning on cancelling it in September, so does anyone know how much it would cost? Thank you:)!

$349 and the full price of the iphone 4

If you transfer your service to Flash Wireless you wont get hit with the cancellation fees of your Verizon contract, then later you can choose to cancel your service or keep it since you are contract free.

I would call Verizon because I tried to cancel my plan and it was almost 2x more then the website said. So it's better to check

Cancellation fee starts at $350 at start of contract and goes down $10 per month. You don't have to pay for the phone.
