Just ordered mine, actually ordered 1 for me and 1 for my wife. Pretty easy process, had to wait an hour for a call back but then it went very smoothly. It was $250 for each, 128 Gb 7+ models and trading in 6+ for both. Hopefully the trade in goes as well, that's the pat that I'm most concerned about.
As far as time goes, the rep said not to expect delivery until mid November, she then gave me a shipping estimate for between sept 23 and oct 10, so not really sure when I'll actually get the phones.
