The recent record-breaking launch of the Apple iPhone 4S proves that it is a favourite, though it isn’t that different from the iPhone 4. The new version, introduced as the “Let’s Talk iPhone” last week, was a little disappointing for those who expected a totally new iPhone 5.

But that doesn’t mean it’s a dud.

Apple has made a number of changes  to improve its performance, as well as creating a new design and features. The new phone includes a faster processor, a better camera, and a new antenna.

The new iPhone features an A5 dual-core 1GHz processor and a dual-core GPU. This combination makes it twice as fast as the older version, as well as much better graphics performance – up to 7 times.

The battery life hasn’t faltered with these improvements, though, with 8 hours of talk time over 3G, 14 hours at 2G, 10 hours of video playback, 40 hours of music playback, and 6 hours of browsing over 3G.

The new iPhone 4s also includes a handy feature called Siri. Siri is a voice assistant that, while doesn’t replace Voice Control one-for-one, is designed to follow commands and bring forth information that you give it.

Siri allows you to, for example, set up reminders, ask for addresses, get directions and even ask random questions. Contact Siri by holding down the Home button. She uses Wikipedia to find facts, and can tell you how many miles it is to Mexico. Pretty neat, eh?

Another plus is that Apple will be developing this further to integrate Siri into a hands-free technology, and you’ll be able to activate her with a Bluetooth headset and, eventually, car integration.

We also love the new camera, an 8-megapixel camera that features a flash, autofocus, f/2.4 aperture lens, and a backside-illuminated CMOS sensor, which lets in  73 percent more light than its predecessors. Color accuracy is improved with its hybrid IR filter, and it also includes a built-in image processor that adds face detection and 26 percent better auto white balance.

Videos are also improved, with enhancements to be able to shoot 1080p HD video clips at 30 frames per second and with video stabilization.

The iPhone 4S is a dual-band world phone, supporting both GSM and CDMA, which will allow users throughVerizon and Sprint customers to use it overseas. For GSM users, it now supports HSDPA 14.4 (download speeds of 14.4Mbps down, 5.8Mbps up).

So all of this is great on the inside, but what does it look like from the outside? Truth be told, the 4s is pretty much the same as the 4, except for 0.1 extra ounce of weight.  It has the same 3.5-inch, 960×640-pixel Retina Display with a glass back and front. It does feature a different–and improved–antenna.

The iPhone 4S is now available for preorder, and goes on sale October 14th from AT&T, Verizon, and Sprint in the U.S. It will come in both black and white colors. The prices start at $199 for the 16GB version, $299 for 32GB, and $399 for 64GB.
