IPhone prices and contracts?

I was thinking about getting an iPhone for Christmas, from the 4s, 5, 5c, and 5s. With a contract for Verizon, how much would each cost for unlimited calling, texting and data. Also, how much would it cost to get them prepaid and for each month?

You can't get unlimited data with Verizon for smart phones. If you are buying on contract, the 4S is free, you can't get the 5 anymore, the 5C is $99 for 16GB and $199 for 32GB. The iPhone 5S is $199 for 16GB, $299 for 32GB, and $399 for 64GB.

Without a contract (prepaid), the iPhone 4S is $450, the 5C starts at $550, and the 5S starts at $650

Verizon contract plans start at $80/month for 500mb
Verizon no contract (prepaid) plans start at $60/month for 2gb

Minimum of $60 - $90 per month depending on the Verizon plan, plus the cost of the iPhone.

iPhone 5S with a 2 year contract:
16 GB - $199
32 GB - $299
64 GB - $399

iPhone 5C with a 2 year contract:
16 GB - $99
32 GB - $199
