This may not be the best place for this, but maybe someone else has encountered the same issue. Within the past 30 days we 'upgraded' to another iPhone 5 for my wife and stuck with AT&T because we get a 25% service discount through her old employer. We were also hit with a $35 'upgrade' fee and I so far have had zero luck getting it removed. This of course led me to shopping around. T-Mobile for two iPhone 5's and unlimited everything is $120 per month and no contract. We pay $110 with our discount, block text/video messages and only have 2gb data for the wife. If we return her phone w/in the 30 day period what happens to the AT&T contract?
