I can upgrade my current phone (Eris) to an Inc2 at this point (15 months into a 2 year deal) if i go through Verizon....BUT....when i try to do so via Costco, or Amazon, I'm stiffled, as they tell me i have to wait until October (at which point all 4 of the phones on our family plan can 'upgrade'). I can get the phone now through Verizon @ $149, but HOW to get around the Costco/Amazon problem now without having to wait till October (and thus for the $79 price), as they only 'recognize' my upgrade date as October?
