The iPhone 4S is the sequel to the iPhone 4. on the contrary to popular belief, in retrospect, is a major new iPhone update. (Pronounced eye - phone - four - S) It features a greatly improved camera, Siri, the A5 chip, and a completely new redesigned antennae system.
The A5 chip offers a dual core operating system which means the iPhone 4S is twice as fast when compared to an iPhone 4. The new Camera takes a new picture faster than any camera phone in the market. It also has an extra lens which makes for sharper more clear pictures. The camera is also 8 megapixels. But keep in mind, the number of megapixels doesn't necessarily mean a better camera. It also has a wider aperture length. Which in other words mean you can get brighter shots, and darker shots. And coupled with the new A5 chip, it takes better pictures than some high end DSLR cameras. The new antennas system offer two antennas. On the iPhone 4, both antennas were sending and receiving data simultaneously. Now with the A5 chip they both do different tasks at the same time. And through this, the iPhone 4S, although only 3G compatible, can reach up to 4G data speeds. And the best way I can explain Siri, is your humble personal assistant. It is a voice recognition software, that can carry on a conversation with you. If you need to do something on your iPhone, just ask Siri. And Siri is available just by holding down the home button.
The iPhone 4S is a major upgrade. And if you owned one, you would know it.
