I ordered a Black 64 GB in-store at 5pm central on the 7th. It's still on backorder and Reps tell me they have no idea when it will ship, only that I just missed the cut-off. The AT&T store closest to me still has a few Black 64GB iPhones left, and I'm debating calling up and getting them to cancel my order so I can pick one up in-store. Has anyone had luck with this? Was it worth it or too much of a headache? I don't want to find out I have to wait a day before I can purchase again or something and then get totally screwed when they run out of phones and I no longer have an order. Any thoughts would be greatly appreciated.
