Your estimate will not update. Your status will just change, and you should get an email. The 10th of October is next Friday. It is not that far away at this point, and your order may change status any day between Today, and next Thursday for shipment with a Tracking Number for overnight delivery.I ordered mine on Sunday, the 21st, and have an estimated delivery date of October 10th. I really don't want to wait that long. I live a few hours east of Chicago
Do you have any Apple or Best Buy stores near you, and have you checked inventory for carrier iPhone in Orange with 256 GB. If you have an urgent need or desire you might want to explore this option.
