Based off tracking notes, seems mine almost didn't make it due to the plane from Kentucky to Maryland being delayed. But looks like all is good now. I think last night it said between 12:30pm and 4:30pm but now says between 1:30pm and 4:30pm. So just an hour delay, no biggie!
If anyone in here ordered with in the first 2 hours of preorders and did not get a tracking yet, then I'd definitely be really frustrated too. If you have not contacted T-Mobile yet, then definitely do that by phone or Twitter chat. Could be that something is hung up or maybe its on the way today but their system is not updating.
