The iPhone 4S has gotten a huge amount of positive feedback upon its announcement and release. So, is the device worth upgrading your original iPhone 4 for the new iPhone 4S phone deals? The iPhone 4S may look just like the original iPhone 4, however there are a number of tweaks inside that make a huge improvement in software and hardware terms.

The new devices biggest leap comes in software terms, however the advent of a dual core processor does it no harm what so ever and really means the device will be more than capable of showing its feathers when it needs to. The new GPU which is seven times as powerful as the previous phone is also a leap and a reason to change phones.

As Mark Hirst the Managing director of Best Mobile Contracts has pointed out,

"Is the iPhone a revolutionary device? No, it is evolutionary, bringing in important upgrades such as dual core processing, a greatly improved graphics chip and Siri, a new voice recognition that learns with you. I look forward to seeing how the iPhone 4S works with iCloud, Apples cloud computing offering as well."

The new Siri is obviously one of the devices most exciting features. The coming of a proper device for voice control makes a huge difference to the phone world. This device offers a whole solution and allows a feasible way for interaction beyond touch screens. This makes it a very important leap and also makes the Apple iPhone 4S a very important jump in tech terms.

The other innovations in the iOS 5 interface are also excellent and also makes a huge difference. The likes of the new iMessages feature, which allows people to send free messages between iPhones makes a huge difference to the phone. The notifications feature is a drop down kind in a similar mould to that of the Android phone and also is a great improvement on the irritation messaging services of old. All of these along with other features are a stride for the iPhone in technology terms.

The iPhone 4S has already sold millions and has only been on sale for a couple of weeks. The amount of people rushing out to buy this phone disguises the fact that for many it is very expensive.
