Apple iPhone 4S Unboxing and Tour

The iPhone 4S was launched in October of 2011, and was announced a day before Steve Jobs death :(

Is has the exact same design as the last year's iPhone 4, BUT the internals are all brand new.

First of all, the iPhone 4S uses the Apple A5 dual core 1Ghz CPU (underclocked at 800 Mhz to preserve battery life), compared to the 1Ghz (again undercloked at 800 Mhz) single core Apple A4 CPU used in the iPhone 4. Besides the CPU, the GPU is also dual core meaning that you get 7x the performance of the iPhone 4, in therms of graphics.

The RAM memory has been upgraded from 256mb to 512mb, and now you can also purchase the 64GB iPhone model.

The 2nd big improvement aside from the increase in speed, is Siri, which is basically your personal assistant. You can ask Siri general things like the weather, random facts, alarm set, music play and much more.

And finally the 3rd big improvement is the camera. The iPhone 4S now features an 8Mp sensor which has been upgraded from the stock 5Mp found in the iPhone 4. But the biggest improvement is the fact that the iPhone 4S utilises ENTIRELY different optics. So Apple has designed a custom-made lens just for the iPhone 4S. It has a lens aperture of 2.4f meaning that more light can be captured be the camera. Also, the backside illumination sensor has been massively improved which translates to better low light photographs.
