i know that i would be able to order the iphone 4 from apples website if i was creating a new contract or adding a line. my question is, will I be able to order the iphone 4 on apple's website taking advantage of the early upgrade AT&T has given me, and still keep my unlimited data plan? To make things a little more complicated, I have a FAN# for a discounted plan. If i upgraded through apple's website, will I also be able to keep my discounted plan? i know this is all possible from AT&T's website, but I don't know if AT&T will offer free shipping on their website. I'll just pay the shipping if apple doesn't offer the upgrade or keep my discounted plan, but I'd like to avoid it if i can. Thanks.
