How much for an IPhone 4S from AT&T?

I have a regular messaging phone from AT&T with unlimited texting and plenty of minutes per month, but no Internet. There are 3 other similar phones on our account. We would like to upgrade one of these phones to an iPhone 4S with Internet. Our two year contract is not up, so could we upgrade? If so, how much?

5 Stars to the best answer!

If all four of your phones are not eligible for an upgrade than it would cost around $200 to terminate one of the phones's contract, and then another $200 to purchase the iPhone 4S (This is the 16 Gigabyte model, the more storage space the more expensive the phone.) If you have a phone that has already been through the two year period than you can upgrade to an iPhone 4S without the termination fee, and you would just need to pay for the phone which as i said starts at $200.
