When did the 6S's sell out of launch day delivery? Can I afford to wait until tomorrow evening to order? Any guesses as to when delivery will have slipped to by then? Also - if I order at 3am, I'm assuming my credit card charge will go through instantly? I have a Barclaycard account. I called today and they said I could have 0% on a new purchase, but I needed to wait 24 hours for them to "activate it". Grrrrr. Thoughts?
