Where are you getting the shipping facts from? I ordered a RG 64GB S on the 15th and mine is packed and ready to ship today.
Because I know people at Apple and UPS.
Like I said if you got a notice that it was packed already you're fine! And if they didn't give you that note and it's going out anyway then that's terrific!! But very bad for T-Mobile's reputation because they aren't processing orders as they come.
The other scenario is that planes have been flying back and forth for over a week now full of iPhones. A rose gold shipment could have just come in and UPS filled it without having a chance to get T-Mobile to update people's orders.
