No, your eyes are not deceiving you. In U.S, this Friday, T-Mobile is going to start selling the iPhone 5. And to make it even better, you can get a T-Mobile iPhone 5 for free in exchange for an old iPhone 4 or iPhone 4s. But ‘for free’ includes only the up front fee, not the additional payments.
But, that means that you’ll save $100 as T-Mobile is the only carrier service that is charging only $100 down payment, whereas most of the other services are offering it for $200. Also, if your iPhone 4 or 4s is in a good condition, you could get credit worth up to $120 which can then be used for the monthly payments of the iPhone 5, which is $20 per month. You can also purchase accessories, another phone or use it for your T-Mobile bill.
