So last year I took advantage of the $650 trade in promo with my 6 to upgrade to the 7. Mine was done through AT& T but I believe the other carriers had similar offers. Not enough time has passed so I can't upgrade to the 8 without it costing $$ out of pocket. And of course if you upgrade the device the monthly credit will stop. I was wondering what others who took advantage of this offer last year were planning to do? Upgrade to 8/7S or keep the 7 or upgrade when you are able to at no cost?
