So, as we know (for some reason I'll never get my head around) the iPhone 5S is NOT available for pre-order. How can I guarantee I get one on the 20th of September? I've read from various sites that I can order it on the 20th, but then when would I actually get the device? I could also queue at an Apple Store but I don't really want to do that. Last year, I pre-ordered an iPhone 5 and it went very smoothly with no issues. What can I (or everyone who wants a 5S on release I should say) do to guarantee one? Thanks.
