Mines has been delivered after they changed my delivery from 09/06/17 to 09/07/17 (BUTTT) A late plan caused the delay for the system to change the date. So I called to make sure they can deliver today and they did as promised.
Great to have the phone in my hands is so amazing in black...
Also, guys, if you portal Online on your T-Mobile is showing your IMEI, is basically meaning that they already assign a phone to your order and can possible mean its shipped already. UPS System gets overwheled during preorders for some reason too.
The bottom line is they are shipping sooner than what you think. T-Mobile only charges the payment methond when its ready to ship. So think about this your phone might be already on it's way without you knowing. ;)
