The problem with that is if you purchased a subsidized iPhone through Apple. If that is the case and you dont cancel your order, you will no longer be eligible for the upgrade.
Thats what Im afraid of. Theres just so many risks in my situation. I ordered the 16GB, the most popular one, so they could be sold out, AND my closest Apple store is 5th Ave in NYC! Its gonna be SWARMED with people on 9/21.
This 10/5 date womps.
