Purchasing on those dates and having a $99+ voice plan would make you upgrade eligible on those dates. She just worded it a bit differently. This is not some kind of super complicated math equation, it's more akin to 2+2=4.
I agree but where the confusion comes in is when people are reporting not having a > $99 per month bill and getting early upgrade eligible.
I have yet to hear of someone with a 3GS in hand that got the deal under those circumstances.
To further my point this is what happened to me today...
*639# tells me I am not eligible until 12/18 even though I purchased in July last year.
My bill is around $80 per month.
I call to check if they had any left (this is around 1PM EST).
He said he had one 32GB black and he would hold it for me (couldn't believe that part) if I assured him I would be there within a half hour.
I mentioned that I needed to find if I fell under the early upgrade.
He told me to call 639 and I told him I did already but people were suggesting I go to the store and find out.
He then asks me when I purchased, and I told him July 08.
(Here is where some may get confused).
He told me that as of 6AM this morning they were told anyone who bought around that time was eligible.
Now, if I stopped there, I would echo some of the comments on this thread.
I then mentioned... "even if my bill wasn't over $99?"
He says, "ohhh, ummm, no, you would need to pay the extra $200."
I was all ready to go to the store and find out once and for all until I read in this thread that someone was turned down at the store.
So it looks like my window is closed for today, and probably the next week or two.
It will give me time to see how things shake out.
I fully expect AT&T changing their tune once the original orders are fulfilled.
If not, no biggie, I am perfectly happy with my OS 3.0 3G.
For $299, it was worth the upgrade, for $499, that is insane for what you get.
