You will be able to track the order from "My Orders" section of the website after it gets shipped :)
Seems like Order initiates from Delhi so Delhi should get it first. I am in Chennai. It will be good if Nokia delivers these Pre-Orders before other retailers (like Flipkart).
My shipment started today evening (from Haryana) and says will be delivered by 1st September (in Chennai).
Just login to your page, and go to order history, there you can see a Tracking Info. button
