Sadly I couldn't pre-order my iPhone 7 plus because all times the app and the website was giving me errors and errors. Instead I received an reservation number and something that says "We have an iPhone for you". I was trying more than 20 times and ships was Fri sept.16, now have changed. This reservations means that I will stay with the Fri sept.16 day? Because I received when that was the date. Any information about this?
