I got the AT&T Gold iPhone 6 Plus 128 GB on launch day. I stood in line at the Apple store at 1:40 PM on launch day friday. At the time, No 6 Plus was in stock at all, so I made a reservation pass for the 6.
One hour later, Apple guy asked if anyone wanted a 6 Plus. So I asked. I changed my reservation for the 6 Plus instead. They had a gold 6 Plus. I wanted Silver but did not have any in-stock.
Some people might ask how I got the 6 Plus in the afternoon. Well apparently, some people might have changed their mind about their order and went for something else. But I was surprised that even at 2 PM, there were some 6 Plus's available.
