That said, if you're looking to upgrade your iPhone, or swapping from a different handset, the Apple iPhone 4S is a fantastic smartphone. Stylish, well made, easy to use and packed with features, there's loads to like.

On the face of it, the Apple iPhone 4S looks identical to the Apple iPhone 4; That's no bad thing, as even a year on, it's still one of the nicest looking smartphones on the market; It also offers the best quality, proving tactile and strong.

If you don't think you'd use Siri, you'd be just as well sticking to the Apple iPhone 4 over the iPhone 4S; Sure, the camera is better, but there's nothing wrong with the iPhone 4's 5-megapixel snapper.

The iPhone 4S needs no introduction. It has sold so many pre-orders that it has already been declared a smash hit even before it was available for sale. Now, at long last, we've gotten our hands on one, and it lives up to the hype, and then some.

Still beautiful; much faster A5 dual core CPU; better camera and Siri

Apple's iPhone 4S, at first glance, seems largely to be a refreshed iPhone 4. It is, but it also is not, thanks to three powerful new features that transform what has been the world's most popular smartphone into a vastly improved new version of itself.

A new iPhone is here and it's called the iPhone 4S. It may not have been the iPhone 5 the tech world was expecting: the iPhone 4S has an almost identical physical design to the previous iPhone 4. However, it boasts a number of improvements that make it a worthy upgrade provided you're coming from an iPhone 3G or iPhone 3GS. For iPhone 4 owners, however, the iPhone 4S is less appealing — even if it remains a fine smartphone in its own right.

If you're upgrading from an iPhone 4, Apple's new iPhone 4S is best described as an evolutionary rather than revolutionary upgrade. However, for current iPhone 3G and 3GS users, or those switching from another platform, the iPhone 4S is a significant upgrade. A higher quality camera and video recorder, a faster processor, a better graphics chip, more memory options and Siri voice control make this one of the best smartphones on the market.

Excellent performance; Improved 8-megapixel camera; Siri voice assistant;

Identical design to predecessor; Upgrading from an iPhone 4 less appealing;

Some say the iPhone 4 is the best iPhone yet. I'm not so sure. It ought to be, and on paper it certainly is, but in the flesh it isn't. This is Apple's third iPhone design, yet it feels in some ways like its first.

Do you want an iPhone, and only an iPhone? If no other phone will do, Apple's iPhone 4S on Virgin Mobile ($649.99) is a very good deal. But if you're open to the huge world of Android phones , there's no way to justify the massive price difference between Virgin's iPhone and its other successful...

The cheapest iPhone 4S available today; if you include the plan price

No 4G; Much more expensive than other Virgin Mobile smartphones
