I'm in the same boat as you almost exactly, including same phone and carrier. I didn't note the time, but 3:04 ET is probably exactly about when my order was placed. It seems like they either had a significantly lower supply and/or higher demand for T-Mobile than other carriers.No charge here yet. Ordered two phones, one at 12:04 Pacific and the other at 12:13 Pacific. Both have 9/28 - 10/5 dates. Ordered through Apple Store app. T-Mobile 256 SG Max.
