The iPhone 4S will be loaded with the Apple A5 chip found in the iPad 2. It’s a dual-core processor with a 1GHz clock-speed, bringing Apple into line with competitors such as the Samsung Galaxy SII that also have dual-core processors in their phones. Apple claims the 4S is up to seven times faster than the current iPhone 4 and graphics in games should also be improved.

The camera has been increased for the iPhone 4S from the 5Mp camera in its predecessor iPhone 4 to 8Mp for the new one. The 8Megapixel camera will shoot 1080p full HD video (720p in iPhone 4) and a custom lens with a larger f/2.4 aperture  lets in 73% more light than the iPhone 4.

Apple has upgraded the memory (RAM) of the iPhone 4S to 1GB (up from 512mb in iPhone 4). This should allow it to run more applications simultaneously and improve speed.

The biggest new feature is a new voice recognition system called ‘Siri’. Siri is a voice controlled personal assistant that is able to do many different tasks with a simple command. Users can ask the phone to find a restaurant, check out the weather, perform searches, send messages,  setting alarm, setting up meetings, asking for directions, and plenty else besides. Siri can also dictate messages back to the user. The English, French, and German languages will be supported.

The iPhone 4S  will go on sale on 14 October, will be available in 16GB, 32GB and 64GB models – in both black and white in the UK, Canada, France, Germany, Japan, and Australia in addition to the U.S.
