iPhone 4S mania is just starting, and going crazy and lucky about it at the same time are one million people who pre-ordered iPhone 4S, only 24 hours after it was first put on sale. Apple boasted that the record as its biggest achievement to date.

Now for people who love numbers, that one million pre-order leaves all Apple records to dust. The iPhone 4, the best selling phone for Apple just raked in 600,000 pre-orders on its first 24 hours, that’s 400,000 pre-orders short of 4S’s record, and what’s even more surprising is that 600k pre-orders come from three iPhone generations combined.

Apple’s press release said that they are blown away with the incredible response to iPhone 4S. That’s coming from the wide disappointment that followed after fanatics learned that they won’t be getting the iPhone 5.

The new iPhone 4S is powered with A5 dual-core chip which is currently the fastest iPhone smartphone processor to date. It also carries an 8 megapixel camera with advanced features including a superior optics and lens and full 1080p resolution for HD video recording.

Another feature is Siri. Siri is an intelligent app that reminds users to get things done easily. Users of iPhone can directly speak to it and command it to do simple tasks like sending SMS, marking an event, setting an alarm, recording a message and more.

iPhone 4S is available in white and black shades. It will be available in Apple stores when they open at 8 am on Friday, October 14, USA time. Expect long lines on these stores as there are people who are already camping out as of this writing.

iPhone 4S is powered with iOS 5. There is a current exploit for the operating system which could be used to jailbreak iPhone 4S, so if you’re the type who’d be looking for that thing, you won’t be needing to wait that long.
