I hate to pay for stuff before it is actually shipped, so, if I order an iPhone 4s through Verizon, my current carrier, will it just add the charges to my bill, or will I have to upfront the bucks via credit card and wait for shipment?
I'm more than positive that you are charged only when it is about to be shipped. I have not had a charge to my credit card and I ordered early this morning. I also receive email alerts immediately from my credit card company whenever I am charged and I have not received any email yet. I also ordered through Verizon, as a new customer.
Apple.com charged me within a few minutes of my pre-order as they did last year. It might come back to the account and then when it's shipped it will be taken out again...
