Apple's new CEO, Tim Cook, has revealed the successor to the iPhone 4, the iPhone 4s. But rather than a full blown successor some might describe this device as an improved version of the iPhone 4. The iPhone 4s boasts a newly redesigned camera lens with 8MP HD upscaled still resolution with a new low light sensor that captures 73% more detail than its predecessor at low light. The lens is also capable of 1080p Full HD video capture with a real time stabiliser and noise reduction filter. Cook remarked that the purpose of these camera 'tweaks' is to put the iPhone 4s as a leader in the point and click camera market. The processor has been replaced by the new A5 dual core processor making computations twice as fast, and giving the ability to handle dual core graphics making the graphical performance of this device seven times quicker than the predecessor. Amongst the core improvements were the overall voice call quality, the battery life, and the integration of a voice operated assistant. In addition to these, the iPhone 4s will sport the new iOS5 which will give way to 200 new features and a better GUI. The exterior design is identical in every possible way. The iPhone 4s will hit the shelves in the UK on the 14th of October and will be available in 16GB, 32GB, and 64GB in either Black or White.
