So Im not available for the early upgrade price until the end of this year and simple want to buy an iphone 4 with no contract ($599). If I buy as an existing customer from apple.com for $599, will they renew my contract anyways/no matter what? Or do I need to purchase from an AT&T store to get one with no commitment? p.s. - In case you didnt notice, I'm doing this so my contract remains on track to expire next year and I will be able to upgrade for the subsidized price.
