I currently have a preorder with AT&T for a iPhone 6+ 128GB in Gold. However, my ship date is currently between 10/31 - 11/11. I am going to wait until Thursday to see if I receive any tracking information that would suggest receiving my phone sooner than projected. If not, I plan to get in line at my nearest AT&T store. Hopefully I can get there early enough to purchase the phone I want from their release stock and cancel the preorder that has yet to ship. Does anyone know if this is doable?
