So I plan to purchase the iPhone 6 on Friday, 9/12-which version I haven't decided yet. So I called Apple to determine at what time on September 12 I could pre-order the iPhone-exactly at the stroke of midnight or 6AM, or whatever? Couldn't get an answer-said he didn't know-didn't believe him but couldn't go any further. Any of you have experience in the past placing a pre-order?
