We have 2 iPhone 4S which we got in October 2011. When I checked my account on AT&T's web site, it says both lines are eligible for the fully subsidized upgrade price. However, when I checked my contract, it won't end until October 2013. Is AT&T making exceptions because the new iPhones will launch on September 20? We are most likely switching carriers, but we're not sure if being eligible for the upgrade means we are out of contract now given the information above. Does anyone have any idea? Thanks.
