Quick question: if you choose to do the early upgrade with at&t (paying the additional $250), does that in affect 'reset' your full subsidy upgrade to 2 years again? I.e. my full upgrade is Sept 2014, if I pay the extra for the early upgrade when the 5s comes out will my full upgrade stay Sept 2014 or be pushed back to 2015? Just trying to figure out what would be cheaper, doing the early upgrade option or buying an iPhone outright & then upgrading to the 6 fully subsidized. Thanks!
