I plan on pre-ordering come 3a EST on my iPhone via the Apple Store. I have gone through most of the checkout process where I selected the carrier, size and color and all that. Paying in full and utilizing the Give Back program to trade in my X. I am now at the Summary screen where obviously the Continue button is fuzzed out. I assume come 3a EST the continue button will light up or will I have to refresh and select everything again from scratch? I also plan on having my laptop and iPad next to me as a back up. Any advice and input welcome. TIA!
