I will be ordering online on the 15th and am curious what has history shown as a time of night or morning that they have started taking pre-order in the past? I worry that if I make my order late in the day that I will be at the end of the list and may not get mine on day1. Is this possible to get mine after thousand of others have already pre-ordered and mine be pushed back a day or two so the early orders are filled first? Just want to prepare and be online ready to place my order at whatever time of night it may possibly be. Thanks for any info you can provide. Obviously there is no way of knowing but this is the 4th iPhone so 3 others in the past may give us an idea on when to be ready.
