I think *639# is your correct day. The website is just weird and says I am eligible on one line (the one with the iP4 bought on launch day).

When I click on "Upgrade Eligibility" next to the paragraph that says I am ready for an upgrade, it opens a new page that says I am not eligible until 11/23/11.

Maybe I shouldn't have included images, but no one seems to be understanding this so I wanted to reiterate it. It says the same thing for everyone on that first page... It's just letting you know that because you're an AT&T customer you will
at some point get a discount when renewing your contract. You have to click "Upgrade eligibility" to actually see what your, um, eligibility is for an upgrade.
Thanks for taking the time to create this post astral, very helpful for all the folks that AT&T confused. Not cool!
And as far as the few of you that mentioned your upgrade went from 6/19 to 11/19 (or whatever) it's looking same for me, but with a different set of months. It extended an similar amount of time. Weird, and also bad.
