Try going to the Track Tab of UPS.com then search by reference and enter your cell number. That's how I found my details. T-Mobile still hasn't been updated. They have really dropped the ball on this whole pre-order even a week after their first mistake!
That's very helpful, thanks. I hadn't received a tracking number yet from T-Mobile but doing that I can see that my phone is out for delivery. Now if it was only going to me directly instead of an address across the country (family plan, account billing address is not mine), that'd be more exciting. Instead I'll wait until sometime next week when it gets shipped to me for real.
I can wait, I don't have to have the phone this very second.
