How much is it to upgrade to an iphone 5c?

I'm with verizon wireless and i have had just a regular iphone 4 for about 2 1/2 years. Someone on my plan is ready for an upgrade so imma take their upgrade to get an iphone 5c. How much will it cost to upgrade? For a 16gb? For a 32 gb? And can they transfer all my messages, photos, videos, music, contacts, etc to my new phone? I know i have to have icloud but how do you know if icloud is turned on?

If you are going for the two year price I believe you should be able to get it for no more than $199.99 plus tax. Do you have a computer at home with itunes? If you do you can manage most of your content mentioned above (except for non-iMessage messages- those sent to non-ioS devices).
