3+ years ago I upgraded my phone at an ATT store to an iphone5S, I think it cost about $200. My wife wants to upgrade her iphone5 so I was shopping online. All of the upgrades to 6 or 7 seem to be very much more expensive, in the $600+ range. Do they not do cheap upgrades anymore or are these prices the prices without a carrier plan? Are the carriers trying to get people to go with monthly payment plans for the phone itself instead of one time payment?
