I agree, and having a tracking number myself, that doesn't mean TMobile has assigned IMEI's yet. All they've done is created UPS labels, which anyone or any business can do online. That part doesn't require the phone to be on hand, printing out the shipping label doesn't require a IMEI to be assigned, they don't list the IMEI on the shipping label.I don't think T Mobile would assign IMEI and print out labels without having the phone physically. My guess is the ones that have tracking like myself, are currently in transit to UPS and with so many phones that process can take 24 hours. I say we see some scans today with delivery by tomorrow.
