I placed my 1st order for jet black 256 plus at 2:45 est (15min before launch time). The est delivery was 9/28. However some started ordering even earlier than that, I could've as well but couldn't figure out how to add the $650 promotion. During that time say 2:30am est, the delivery date was 9/16. So I assume many orders went through prior to official launch.
I have my doubts that the iPhone will arrive earlier than the expected date. Here's why in years past Verizon went live about 5min earlier and if you got your order fairly quick, maybe 10min tops after launch - you had the chance of getting the phone on release date. This year orders went live nearly 40min prior to launch. So if you ordered at 3:05 est, essentially it's almost like placing an order 40-45min after launch on any other year.
Hope I'm wrong but it isn't a big deal for me to wait if I have to.
