How much would I have to pay total if I upgrade to the iPhone 5S for AT&T?

I've been eligible for an upgrade for a while now and I want to buy the 5s. Currently I have the 3GS. Old lol. This is the message I got when I checked it.

Congratulations! You are upgrade eligible. Check out AT&T Next which lets you upgrade to a new device every year with no upgrade fees.

Most likely you would only need to pay for the phone, Which I believe is $200 + Tax/Activation Fee (You only get it at this price if you sign a new 2 year contract). You already have data on your old phone so that would just transfer over to your new monthly payments. I think activation fees are usually waived though.

$199 for a 16 gig, $299 for a 32, and $399 for a 64. You will also have to pay a $36 activation fee. If you get it at Best Buy, you can get 6 months no interest financing. If you spend $429, you can get 18 months financing. I did that and got an otter box to get the financing.

The Next thing is scammy, as far as I'm concerned. It's a monthly fee for the phone. When you add up the payments, it's substantially higher than buying it outright, but if you can't afford to buy it outright, it may be your only option.

I got mine Friday and it is slick.
