The original 3 that I ordered on release weekend were 32 Gb. Those are the ones that came in 2 weeks. The next order was the 2 64 Gb that I ordered this week. The Black one has not been updated. But the White one is the one that says it shipped the same day the order was placed. Guess I will find out if it is true on Monday when the package arrives.
I did order a USB Car Charger on the same order. So it may be that just the car charger shipped today. But, I also ordered Car Chargers with the other 3 iPhones. They held the chargers and shipped them at the same time, and in the same box as, the iPhone 5's. Assume that they would do the same for this order. I will come back and post one way or the other on Monday.
As for the charging before it ships. Mine is a business account and all hardware upgrades are added on to our corporate account. But I can tell you that it sometimes take extra billing cycles before the charges show up. Most likely due to shipping dates being close to the billing date, or something similar. So that makes it seem like they do not charge until it ships.
