I ordered a silver 64gb iPhone SE on the 26th of December and received a verification email saying my order had been placed and would be delivered etc. At the time of order it said that the phone was in stock and would be delivered however they now say backorder for these devices. The Christmas delivery dates said it would be delivered by the 3rd of January, however I can still not track the devices delivery.
We can confirm this popular handset is currently on backorder, it is regrettable if there was a miscommunication on delivery turnaround times. Once the phone has been dispatched you will be able to track it here.
