I purchased an iPhone 4 via pre-order from Apple's site on the first day you could order. I was fully qualified for an upgrade and purchased a 32gb for $299+tax. It arrived a day early like it did for many users. Shortly after arrival i checked my upgrade eligibility with AT&T out of curiosity and it showed, as expected, that I was not qualified for any upgrade and would again be qualified in about 12 months. Fast forward to a few days ago, i checked eligibility of some lines on my account and my line is already qualified for an early upgrade less than a month after I already upgraded. I am curious why I am eligible so soon, but more importantly if i were to take advantage of the early upgrade how quickly would I be eligible again. I am thinking about buying a white iPhone 4 if it ever comes out and selling mine, or just purchasing another black iPhone 4, unlocking it and selling it. If anyone had something similar happen with their upgrade eligibility or knows anything more, let me know.
