I cant get past the "upgrade eligibility" link. What browser are you using?
I got this same message. When I checked my order status later it said that everything was on backorder but I ordered at 5 am this morning! Could my early order really be backordered?
i see this:
OS001: We're sorry but the information you entered was not recognized by our systems. Please contact us for further assistance.
my order was submitted about 1 hr ago
I'm using IE, try clearing your cookies, etc
Can you order 3 iPhone 4's on AT&T's website for upgrades before you checkout, or do you have to do 1 at a time?
It isn't available until the 24th so I would expect it to be back ordered until closer to that date.
The order number didn't work for me either but using my phone number worked.
