iPhone 4S features

Have you ever asked your self why iPhone S4 is called iPhone S4? and what is this S stands for?

And why it was called iPhone 4S, not for example  iPhone 5?

Tell this moment no one knew what "S" stands for, but some people said it stands for "Super" or "Speed" maybe "Special", and why is it called "4" cause it looks exactly like iPhone 4.

But what is super or special about iPhone S4? 

Speed is one of the main features any one is looking for when using any electronic device, but if we compared between iPhone 4 and iPhone 4S, if we say that an application needs 3 seconds to start up in iPhone 4, it will only need around a second or little more to start up.

Looking to the camera, iPhone 4 had a camera of 4 megapixels only, but the new S4 is 8 mega pixel with 1080p video recording quality.

Siri technology

All the previous data sounds great but sill asking what are the other unique things, the unique thing in iPhone S4 is the voice control feature, most of previous iPhones including iPhone 4 are having a problem with the voice control feature, but with iPhone 4S i open my phone book and made calls, sent emails, find directions and did a lot of stuff using the Siri feature.
