Ordered JB 256 7+ on morning of pre-order release. Ordered AT&T Next replacement from Apple. Got a November promise which changed to Nov 18 two weeks ago.
Checked istocknow this morning, Saturday 22 Oct about 7:30 AM and found one in stock at Apple Store an hour away. Placed a reservation on apple with that store for 1:00 PM pick-up.
Called store when it opened to confirm they physically had phone, which they confirmed. Cancelled September order to get back upgrade availability from AT&T. This showed able to upgrade within five minutes on AT&T site.
Drove to store, completed transaction with Next upgrade for one year, bought AppleCare+ and paid tax for phone. Walked out in 20 minutes.
Got home, activated JB 7 Plus using iCloud backup I saved from that morning. Kept phone on ice pack as it loaded backup, apps, pictures, mail, etc. Sending this from new phone.
First impression is everything is way faster than 6s Plus. Feels great, no issues, easy peasy. Only thing left to do is mail old phone to AT&T and get refund for second year of applecare+ on old phone.
So happy I didn't have to wait another four weeks!!!
Good luck to everyone.
