One lesson that iPhone fanatics learned through the years is that if there will be a new version coming out, secure your preorder ASAP. And sadly enough, those who ordered their iPhone 4S won’t be getting any unit on the launch date.

Apple originally set the delivery of iPhone 4S on October 14 which marks as the first day the users will be able to hold the new iPhone. But after a while, Apple updated their website saying that those who preordered the new phone can expect to get them in one to two weeks time.

We don’t know yet if this change in schedule has anything to do with Steve Jobs demise, regardless iPhone fanatics are still eager on getting the new iPhone, as long as it’s not the iPhone 5 being sold in China.

This is bad news to other iPhone 4S owner wannabes however; as this news suggests that iPhone 4S on the launched date at least thru the Apple store are already sold out. But if you think that we won’t be seeing epic long lines that we’ve seen in past iPhone launches then you’re wrong. Those who want to grab iPhone 4S earlier than most of the population can still try to grab one right Apple stores’ opening on Friday morning. Mashable blog already noted that there are at least three people queeing for an iPhone 4S at Apple store in 5th Avenue, New York City.

That waiting may be too crazy or at least too early to some but basing on AT&T’s statistics that level of excitement is very much justifiable. AT&T said that they already received more than 200,000 preorders for the smartphone with just 12 hours of pre-availability, proving the iPhone 4S launch to be Apple’s most successful to date.
